Spin susceptibilities in magnetic type-I and type-II Weyl semimetals
Feng Xiong, Xingjie Han, Carsten Honerkamp
We investigate interacting spin susceptibilities in lattice models for -reversal symmetry-broken Weyl semimetals. We employ a random phase approximation (RPA) method f…
Investigation of the effective interactions for the Emery model by the constrained random-phase approximation and constrained functional renormalization group
Xing-Jie Han, Philipp Werner, Carsten Honerkamp
The effective interaction of downfolded low-energy models for electrons in solids can be obtained by integrating out the high energy bands away from the target band near the Fermi…
Statistical inference and feasibility determination: a nonasymptotic approach
Ying Zhu
We develop non-asymptotically justified methods for hypothesis testing about the dimensional coefficients in (possibly nonlinear) regression models. Given a function $h…
Analytic continuation with Padé decomposition
Xing-Jie Han, Hai-Jun Liao, Hai-Dong Xie +3
The ill-posed analytic continuation problem for Green's functions or self-energies can be done using the Padé rational polynomial approximation. However, to extract accurate result…
Phase transition of the q-state clock model: duality and tensor renormalization
Jing Chen, Hai-Jun Liao, Hai-Dong Xie +6
We investigate the critical behavior and the duality property of the ferromagnetic -state clock model on the square lattice based on the tensor-network formalism. From the entan…
Charge dynamics of the antiferromagnetically ordered Mott insulator
X. J. Han, Y. Liu, Z. Y. Liu +5
We study the charge dynamics of the half-filled Hubbard model on the square lattice at zero temperature. We employ a slave-fermion formulation in which the charge degrees of freedo…
Ground State Degeneracy of Interacting Spinless Fermions
Zhong-Chao Wei, Xing-Jie Han, Zhi-Yuan Xie +1
We propose an eigen-operator scheme to study the lattice model of interacting spinless fermions at half filling and show that this model possesses a hidden form of reflection posit…
