Sign problem free quantum Monte-Carlo study on thermodynamic properties and magnetic phase transitions in orbital-active itinerant ferromagnets
Shenglong Xu, Yi Li, Congjun Wu
The microscopic mechanism of itinerant ferromagnetism is a long-standing problem due to the lack of non-perturbative methods to handle strong magnetic fluctuations of itinerant ele…

Time-reversal Invariant SU(2) Hofstadter Problem in Three Dimensional Lattices
Yi Li
We formulate the lattice version of the three-dimensional SU(2) Landau level problem with time reversal invariance. By taking a Landau-type gauge, the system is reduced into the on…

The honeycomb lattice with multi-orbital structure: topological and quantum anomalous Hall insulators with large gaps
Gu-Feng Zhang, Yi Li, Congjun Wu
We construct a minimal four-band model for the two-dimensional (2D) topological insulators and quantum anomalous Hall insulators based on the - and -orbital bands in the…
