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…

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…
