Title: TRACK: A python code for calculating the transport properties of correlated electron systems using Kubo formalismSubjects: Strongly Correlated Electrons (condmat.strel)
Exploring the transport properties of different materials brings new avenue for basic understanding of emergent phenomena and practical applications in many different fields. Here, we report a program named as TRACK (TRAnsport properties for Correlated materials using Kubo formalism) which is written in Python 3 for calculating temperature dependent electrical conductivity, electronic part of thermal conductivity, Seebeck coefficient and Lorenz number. In this code, Kubo linearresponse formalism is utilized for computing these parameters using both interacting and noninteracting electronic structure methods. The formula for transport coefficients is accordingly modified to obtain the transport parameters under relaxation time approximation using bandtheory. The basic inputs of this program are the structural information, dense kpoints sampling in the irreducible part of the Brillouin zone and the information of velocity matrix elements, which can be calculated using thirdparty abinitio package. TRACK is expected to calculate the transport properties of different class of materials. The code has been benchmarked by performing calculation on three different types of materials namely Vanadium (V), FeSi and LaCoO$_3$, which are metal, semiconductor and Mott insulator, respectively. The temperature dependent behaviour of the transport coefficients for these materials show fairly good agreement with the corresponding experimental data.

Title: Chern number matrix of nonAbelian spinsinglet fractional quantum Hall effectComments: 5 pages, 4 figuresSubjects: Strongly Correlated Electrons (condmat.strel)
While the understanding of Abelian topological order is comprehensive, how to describe the internal correlation structure of nonAbelian states is still outstanding. Here, we propose a general scheme based on the manybody Chern number matrix to characterize the nonAbelian multicomponent fractional quantum Hall states at filling factions $\nu = 2k/(2kM + 3)$ ($k,M\in Z$). As a concrete example, we study the manybody ground states of twocomponent bosons in topological flat band models. Utilizing densitymatrix renormalization group and exact diagonalization methods, we demonstrate the emergence of the nonAbelian spinsinglet fractional quantum Hall effect under threebody interaction at a total filling factor $\nu=4/3$ in the lowest Chern band, whose topological nature is classified by sixfold degenerate ground states and fractionally quantized Chern number matrix.

Title: MuFinder: A program to determine and analyse muon stopping sitesAuthors: B. M. Huddart, A. HernándezMelián, T. J. Hicken, M. Gomilšek, Z. Hawkhead, S. J. Clark, F. L. Pratt, T. LancasterComments: 9 pages, 5 figuresSubjects: Strongly Correlated Electrons (condmat.strel)
Significant progress has recently been made in calculating muon stopping sites using density functional theory. The technique aims to address two of the most common criticisms of the muonspin spectroscopy ($\mu^+$SR) technique, namely, where in the sample does the muon stop, and what is its effect on its local environment. We have designed and developed a program called MuFinder that enables users to carry out these calculations through a simple graphical user interface (GUI). The procedure for calculating muon sites by generating initial muon positions, relaxing the structures, and then clustering and analysing the resulting candidate sites, can be done entirely within the GUI. The local magnetic field at the muon site can also be computed, allowing the connection between the muon sites obtained and experiment to be made. MuFinder will make these computations significantly more accessible to nonexperts and help to establish muon site calculations as a routine part of $\mu^+$SR experiments.

Title: Nonperturbative Superexchange Interaction for High Curie Temperature in Intrinsic Magnetic SemiconductorComments: 6 pages, 4 figuresSubjects: Strongly Correlated Electrons (condmat.strel); Mesoscale and Nanoscale Physics (condmat.meshall)
Here a nonperturbative superexchange interaction is unveiled in covalency scheme which allows longrange ferromagnetic exchange interactions, thus naturally gives intrinsic roomtemperature ferromagnetic semiconductors. To realize such a scheme in transition metal compounds, two comparable energy scales are indispensable: i) the electronelectron interactions are comparable to the onsite energy difference between ligand p and metal d orbitals and ii) the hopping strengths between p and d orbitals are comparable to their band widths. Guided by these principles, a paradigm based on firstprinciples calculation and Wannier downfolding is then built to search for realistic materials. Through thorough physical parameter mining on 36 FeSelike trilayer structures, CrAs monolayer is mapped out to belong to covalency scheme, which possesses a band gap $\sim$ 0.45 eV, ferromagnetic nearest/nextnearestneighbor exchange coupling strength $\sim$ 57/40 meV, and correspondingly a high Curie temperature about 1500 K.

Title: Densitymatrix functional theory of the attractive Hubbard model: Statistical analogy of pairing correlationsSubjects: Strongly Correlated Electrons (condmat.strel)
The groundstate properties of the Hubbard model with attractive local pairing interactions are investigated in the framework of lattice densityfunctional theory. A remarkable correlation is revealed between the interactionenergy functional $W[\boldsymbol{\eta}]$ corresponding to the Blochstate occupationnumber distribution $\eta_{\boldsymbol{k}\sigma}$ and the entropy $S[\boldsymbol{\eta}]$ of a system of noninteracting fermions having the same $\eta_{\boldsymbol{k}\sigma}$. The relation between $W[\boldsymbol{\eta}]$ and $S[\boldsymbol{\eta}]$ is shown to be approximately linear for a wide range of groundstate representable occupationnumber distributions $\eta_{\boldsymbol{k}\sigma}$. Taking advantage of this statistical analogy, a simple explicit ansatz for $W[\boldsymbol{\eta}]$ of the attractive Hubbard model is proposed, which can be applied to arbitrary periodic systems. The accuracy of this approximation is demonstrated by calculating the main ground state properties of the model on several 1D and 2D bipartite and nonbipartite lattices and by comparing the results with exact diagonalizations.

Title: Fulfillment of sum rules and Ward identities in the multiloop functional renormalization group solution of the Anderson impurity modelAuthors: Patrick ChalupaGantner, Fabian B. Kugler, Cornelia Hille, Jan von Delft, Sabine Andergassen, Alessandro ToschiSubjects: Strongly Correlated Electrons (condmat.strel)
We investigate several fundamental characteristics of the multiloop functional renormalization group (mfRG) flow by hands of its application to a prototypical manyelectron system: the Anderson impurity model (AIM). We first analyze the convergence of the algorithm in the different parameter regions of the AIM. As no additional approximation is made, the multiloop series for the local selfenergy and response functions converge perfectly to the corresponding results of the parquet approximation (PA) in the weak to intermediatecoupling regime. Small oscillations of the mfRG solution as a function of the loop order gradually increase with the interaction, hindering a full convergence to the PA in the strongcoupling regime, where perturbative resummation schemes are no longer reliable. By exploiting the converged results, we inspect the fulfillment of (i) sum rules associated to the Pauli principle and (ii) Ward identities related to conservation laws. For the Pauli principle, we observe a systematic improvement by increasing the loop order and including the multiloop corrections to the selfenergy. This is consistent with the preservation of crossing symmetries and twoparticle selfconsistency in the PA. For the Ward identities, we numerically confirm a visible improvement by means of the Katanin substitution. At weak coupling, violations of the Ward identity are further reduced by increasing the loop order in mfRG. For larger interaction values, the overall behavior becomes more complex, and the benefits of the higherloop terms are mostly present in the contributions at large frequencies.

Title: Jellium at finite temperatureAuthors: Riccardo FantoniComments: 30 pages, 4 figures, 1 tableSubjects: Strongly Correlated Electrons (condmat.strel); Materials Science (condmat.mtrlsci); Quantum Gases (condmat.quantgas); Statistical Mechanics (condmat.statmech); Computational Physics (physics.compph)
We adopt the fixed node restricted path integral Monte Carlo method within the "Worm algorithm" to simulate Wigner's Jellium model at finite, non zero, temperatures using freeparticle nodes of the density matrix. The new element is that we incorporate the Worm algorithm paradigm of Prokof'ev and Svistunov in the grand canonical ensemble in order to more efficiently handle the fermionic exchanges. We present results for the structure and thermodynamic properties of the ideal Fermi gas and three points for the interacting electron gas. We treat explicitly the case of the partially polarized electron gas.

Title: Unconventional Planar Hall Effect in Kagome Metal KV$_3$Sb$_5$Subjects: Strongly Correlated Electrons (condmat.strel)
Exploration of novel transport behavior in correlated topological materials is of great importance and interest for revealing exotic orders and states. Recently, a new family of kagome materials AV$_3$Sb$_5$(A=K, Rb, Cs) was discovered which hosts chiral charge density wave (CDW), superconductivity, and topological nontrivial states, etc, providing a new platform to study the correlated and topological physics. In this letter, we report the observation of unconventional planar Hall effect (PHE) and anisotropic magnetoresistivity (PAMR) in KV$_3$Sb$_5$. At low temperatures, with increasing the applied field, PHE and PAMR exhibit more and more prominent highfold symmetrical oscillations with the rotating angle instead of only regular twofold symmetrical oscillation which violates the conventional empirical law. These highfold such as fourfold or sixfold symmetrical oscillations exhibit strong temperature and field dependence and varnish at high temperatures or low fields. In addition, the anisotropic inplane magnetoresistivity is revealed to exhibit nonmonotonous behavior and strong angulardependent evolution. The abnormal inplane transport properties suggest a significant interplay among the anisotropic magnetic correlation, lattice, and electronic structure in KV$_3$Sb$_5$.

Title: Topological chargeentropy scaling in kagome Chern magnet TbMn$_6$Sn$_6$Authors: Xitong Xu, JiaXin Yin, Wenlong Ma, HongRu Tian, XiaoBin Qiang, Huibin Zhou, Jie Shen, Haizhou Lu, TayRong Chang, Zhe Qu, Shuang JiaComments: 14 pages, 3 figuresSubjects: Strongly Correlated Electrons (condmat.strel)
In ordinary materials, electrons conduct both electricity and heat, where their chargeentropy relations observe the Mott formula and the WiedemannFranz law. In topological quantum materials, the transverse motion of relativistic electrons can be strongly affected by the quantum field arising around the topological fermions, where a simple model description of their chargeentropy relations remains elusive. Here we report the topological chargeentropy scaling in the kagome Chern magnet TbMn$_6$Sn$_6$, featuring pristine Mn kagome lattices with strong outofplane magnetization. Through both electric and thermoelectric transports, we observe quantum oscillations with a nontrivial Berry phase, a large Fermi velocity and twodimensionality, supporting the existence of Dirac fermions in the magnetic kagome lattice. This quantum magnet further exhibits large anomalous Hall, anomalous Nernst, and anomalous thermal Hall effects, all of which persist to above room temperature. Remarkably, we show that the chargeentropy scaling relations of these anomalous transverse transports can be ubiquitously described by the Berry curvature field effects in a Cherngapped Dirac model. Our work points to a model kagome Chern magnet for the proofofprinciple elaboration of the topological chargeentropy scaling.

Title: Superconductivity in a minimal twoband model for infinitelayer nickelatesComments: 11 pages, 2 figures + 3 pages, 4 figuresSubjects: Strongly Correlated Electrons (condmat.strel)
While the recent discovery of superconductivity in infinitelayer nickelates has drawn considerable attention, a common ingredient of the fundamental building blocks to describe their ground states has been lacking. A series of experimental and theoretical studies have suggested that an effective twoband Hubbard model with Ni 3$d_{x^2y^2}$ and rareearth ($R$) 5$d$ character may describe the lowenergy physics. Here, we study the ground state properties of this twoband model on fourleg cylinders using the densitymatrix renormalization group (DMRG). At halffilling, the ground state of the system is consistent with a Luttinger liquid, possessing quasilongrange charge and spin correlations in the $R$ layer, but shortrange correlations in the Ni layer. At a hole doping concentration of $\delta=12.5\%$, the $R$ layer is nearly empty and the ground state of the system is consistent with a LutherEmery liquid, where we find powerlaw superconducting and charge density correlations in the Ni layer, but exponentially decaying spin correlations. The consistency of our results with experimental observations may help to reveal the microscopic mechanism for pairing in these nickelates and other unconventional superconductors.

Title: Pivot Hamiltonians as generators of symmetry and entanglementSubjects: Strongly Correlated Electrons (condmat.strel); Statistical Mechanics (condmat.statmech); Quantum Physics (quantph)
It is wellknown that symmetryprotected topological (SPT) phases can be obtained from the trivial phase by an entangler, a finitedepth unitary operator $U$. Here, we consider obtaining the entangler from a local 'pivot' Hamiltonian $H_{piv}$ such that $U = e^{i\pi H_{piv}}$. This perspective of Hamiltonians pivoting between the trivial and SPT phase opens up two new directions which we explore here. (i) Since SPT Hamiltonians and entanglers are now on the same footing, can we iterate this process to create other interesting states? (ii) Since entanglers are known to arise as discrete symmetries at SPT transitions, under what conditions can this be enhanced to $U(1)$ 'pivot' symmetry generated by $H_{piv}$? In this work we explore both of these questions. With regard to the first, we give examples of a rich web of dualities obtained by iteratively using an SPT model as a pivot to generate the next one. For the second question, we derive a simple criterion guaranteeing that the direct interpolation between the trivial and SPT Hamiltonian has a $U(1)$ pivot symmetry. We illustrate this in a variety of examples, assuming various forms for $H_{piv}$, including the Ising chain, and the toric code Hamiltonian. A remarkable property of such a $U(1)$ pivot symmetry is that it shares a mutual anomaly with the symmetry protecting the nearby SPT phase. We discuss how such anomalous and nononsite $U(1)$ symmetries explain the exotic phase diagrams that can appear, including an SPT multicritical point where the gapless ground state is given by the fixedpoint toric code state.

Title: Chiral central charge from a single bulk wave functionComments: 4+5 pages, 6 figuresSubjects: Quantum Physics (quantph); Strongly Correlated Electrons (condmat.strel)
A $(2+1)$dimensional gapped quantum manybody system can have a topologically protected energy current at its edge. The magnitude of this current is determined entirely by the temperature and the chiral central charge, a quantity associated with the effective field theory of the edge. We derive a formula for the chiral central charge that, akin to the topological entanglement entropy, is completely determined by the manybody ground state wave function in the bulk. According to our formula, nonzero chiral central charge gives rise to a topological obstruction that prevents the ground state wave function from being realvalued in any local product basis.

Title: Absence of superdiffusion in certain random spin modelsComments: 4+3 pagesSubjects: Statistical Mechanics (condmat.statmech); Strongly Correlated Electrons (condmat.strel); Quantum Physics (quantph)
The dynamics of spin at finite temperature in the spin1/2 Heisenberg chain was found to be superdiffusive in numerous recent numerical and experimental studies. Theoretical approaches to this problem have emphasized the role of nonabelian SU(2) symmetry as well as integrability but the associated methods cannot be readily applied when integrability is broken. We examine spin transport in a spin1/2 chain in which the exchange couplings fluctuate in space and time around a nonzero mean $J$, a model introduced by De Nardis et al. [Phys. Rev. Lett. 127, 057201 (2021)]. We show that operator dynamics in the strong noise limit at infinite temperature can be analyzed using conventional perturbation theory as an expansion in $J$. We find that regular diffusion persists at long times, albeit with an enhanced diffusion constant. The finite time spin dynamics is analyzed and compared with matrix product operator simulations.

Title: Supercurrentinduced topological phase transitionsComments: 12 pages, 5 figuresSubjects: Superconductivity (condmat.suprcon); Mesoscale and Nanoscale Physics (condmat.meshall); Materials Science (condmat.mtrlsci); Strongly Correlated Electrons (condmat.strel)
We show that finite current in superconductors can induce topological phase transitions, as a result of the deformation of the quasiparticle spectrum by a finite centerofmass (COM) momentum of the Cooper pairs. To show the wide applicability of this mechanism, we examine the topological properties of three prototypical systems, the Kitaev chain, $s$wave superconductors, and $d$wave superconductors. We introduce a finite COM momentum as an external field corresponding to supercurrent and show that all the models exhibit currentinduced topological phase transitions. We also discuss the possibility of observing the phase transitions in experiments and the relation to the other finite COM momentum pairing states.

Title: On quenches to the critical point of the three states Potts model  Matrix Product State simulations and CFTComments: 9 pages 10 figures, all comments welcomeSubjects: Statistical Mechanics (condmat.statmech); Quantum Gases (condmat.quantgas); Strongly Correlated Electrons (condmat.strel); High Energy Physics  Theory (hepth); Quantum Physics (quantph)
Conformal Field Theories (CFTs) have been used extensively to understand the physics of critical lattice models at equilibrium. However, the applicability of CFT calculations to the behavior of the lattice systems in the outofequilibrium setting is not entirely understood. In this work, we compare the CFT results of the evolution of the entanglement spectrum after a quantum quench with numerical calculations of the entanglement spectrum of the threestate Potts model using matrix product state simulations. Our results lead us to conjecture that CFT does not describe the entanglement spectrum of the threestate Potts model at long times, contrary to what happens in the Ising model. We thus numerically simulate the outofequilibrium behaviour of the Potts model according to the CFT protocol  i.e. by taking a particular product state and "cooling" it, then quenching to the critical point and find that, in this case, the entanglement spectrum is indeed described by the CFT at long times.

Title: Interplay between static and dynamic correlation in itinerant magnets  a first principles study of magnons in MnBiComments: 13 pagesSubjects: Materials Science (condmat.mtrlsci); Strongly Correlated Electrons (condmat.strel)
We present first principles calculations of the dynamic susceptibility in strained and doped ferromagnetic MnBi using timedependent density functional theory. In spite of being a metal, MnBi exhibits signatures of strong correlation and a proper description in the framework of density functional theory requires Hubbard corrections to the Mn $d$orbitals. Here we develop a consistent rescaling of the exchangecorrelation kernel that permits calculations of the dynamic susceptibility that includes Hubbard corrections without deteriorating the delicate balance between the magnon dispersion and the Stoner continuum. We find excellent agreement with the experimentally observed magnon dispersion for pristine MnBi and show that the material undergoes a phase transition to helical order under application of either doping or strain. The presented methodology pave the way for susceptibility calculations of a wide range of magnetic materials that require Hubbard corrections for a proper description of the ground state in the framework of density functional theory.

Title: Dynamics of Negativity of a WannierStark ManyBody Localized System Coupled to a BathComments: 10 pages, 11 figuresSubjects: Disordered Systems and Neural Networks (condmat.disnn); Strongly Correlated Electrons (condmat.strel)
An interacting system subjected to a strong linear potential can host a manybody localized (MBL) phase when being slightly perturbed. This socalled WannierStark or `tiltedfield' MBL phase inherits many properties from the wellinvestigated disordered MBL phase, and provides an alternative route to experimentally engineer interacting localized systems without quenched disorder. In this work, we investigate the dynamics of entanglement in a WannierStark MBL system coupled to a dephasing environment. As an accessible entanglement proxy, we use the third R\'{e}nyi negativity $R_3$, which reduces to the third R\'{e}nyi entropy in case the system is isolated from the environment. This measure captures the characteristic logarithmic growth of interacting localized phases in the intermediatetime regime, where the effects of the coupling to the environment are not yet dominating the dynamics. Thus it forms a tool to distinguish WannierStark MBL from noninteracting WannierStark localization up to intermediate timescales, and to quantify quantum correlations in mixedstate dynamics.

Title: Interacting SPT phases are not Morita invariantAuthors: Luuk StehouwerComments: 22 pages, 1 figureSubjects: High Energy Physics  Theory (hepth); Strongly Correlated Electrons (condmat.strel); Mathematical Physics (mathph); Algebraic Topology (math.AT)
Class D topological superconductors have been described as invertible topological phases protected by charge $Q$ and particlehole symmetry $C$. A competing description is that class D has no internal symmetries except for the fermion parity group $\mathbb{Z}_2^F = \{1, (1)^F\}$. In the weakly interacting setting, it can be argued that `particlehole symmetry cancels charge' in a suitable sense. Namely, the classification results are independent of which of the two internal symmetry groups are taken because of a Morita equivalence. However, we argue that for strongly interacting particles, the group of symmetryprotected topological phases in the two cases are nonisomorphic in dimension $2+1$. This shows that in contrast to the free case, interacting phases are not Morita invariant. To accomplish this, we use the approach to interacting phases using invertible field theories and bordism. We give explicit expressions of invertible field theories which have the two different groups $\mathbb{Z}_2^F$ and $U(1)_Q \rtimes \mathbb{Z}_2^C$ as internal symmetries and give spacetime manifolds on which their partition functions disagree. Techniques from algebraic topology are used to compute the relevant bordism groups, most importantly the James spectral sequence. The result is that there are both a new $\mathbb{Z}_2$ and a new $\mathbb{Z}$invariant for $U(1)_Q \rtimes \mathbb{Z}_2^F$ that are not present for $\mathbb{Z}_2^F$.

Title: A parent Hubbard model for spin1 Haldane chainsComments: 5 pages, 4 figuresSubjects: Mesoscale and Nanoscale Physics (condmat.meshall); Strongly Correlated Electrons (condmat.strel); Quantum Physics (quantph)
The Haldane phase for antiferromagnetic spin1 chains is a celebrated topological state of matter, featuring gapped excitations and fractional spin1/2 edge states. Here we provide numerical evidence that this phase can be realized with a Hubbard model at halffilling, where each $s = 1$ spin is stored in a foursite fermionic structure. We find that the noninteracting limit of our proposed parent model describes a onedimensional topological insulator, adiabatically connected to the Haldane phase. Our work suggests a route to build spin1 networks using Hubbard model quantum simulators.
