Emergence of asymmetric fermionic order in interacting birefringent fermions
Yi-Xiang Wang, Fuxiang Li
The birefringent fermions possess a spectrum with two distinct Fermi velocities. Here based on the lattice model, we use the mean-field method to investigate the interaction-induce…
Spontaneous symmetry breaking of an interacting Chern insulator on a topological square lattice
Yi-Xiang Wang, Dong-Xiang Qi
The interplay between topology and correlation lies at the forefront of modern condensed matter physics. In this paper, we study the extended fermion-Hubbard model, including the o…
Repulsive Fermi gases in a two-dimensional lattice with non-Abelian gauge fields
Yi-Xiang Wang, Fuxiang Li
Motivated by the recent experiment realizing bidirectional spin-orbit-coupled Bose-Einstein condensates (BEC), we theoretically explore the properties of repulsive fermions in the…
Interaction-induced phase transitions of type-II Weyl semimetals
Yi-Xiang Wang, Fuxiang Li, Baoan Bian
The study of Weyl semimetals (WSMs) lies at the forefront of the nontrivial topological phenomena in condensed-matter physics. In this work, we study the effect of on-site repulsiv…
