Excitonic Quantum Anomalous Hall Effect in Collinear Magnets Without Spin-Orbit Coupling
Xingxing Liu, ChaoYang Tan, Peng-Jie Guo +2
Spin-orbit coupling (SOC) is thought to be necessary in realizing quantum anomalous Hall (QAH) insulators in magnetic materials. In this Letter, we propose an exciton-condensation…
Stacking-induced type-II quantum spin Hall insulators with high spin Chern number in unconventional magnetism
Chao-Yang Tan, Panjun Feng, Ze-Feng Gao +3
While stacking two type-I quantum spin Hall insulators typically results in a trivial insulator, the behavior of the assembly of type-II quantum spin Hall insulators remains unexpl…
Type-II quantum spin Hall insulator
Panjun Feng, Chao-Yang Tan, Miao Gao +5
Quantum spin Hall effect is usually realized in two-dimensional materials with time-reversal symmetry, but whether it can be realized without symmetry protection remains unexplored…
Crystal valley Hall effect
Chao-Yang Tan, Ze-Feng Gao, Huan-Cheng Yang +4
The time-reversal symmetry is thought to be a necessary condition for realizing valley Hall effect. If the time-reversal symmetry is broken, whether the valley Hall effect can be r…
Bipolarized Weyl semimetals and quantum crystal valley Hall effect in two-dimensional altermagnetic materials
Chao-Yang Tan, Ze-Feng Gao, Huan-Cheng Yang +3
Magnetism and topology are two major areas of condensed matter physics. The combination of magnetism and topology gives rise to more novel physical effects, which have attracted st…
