Phaseless auxiliary-field quantum Monte Carlo method with spin-orbit coupling
Zheng Liu, Shiwei Zhang, Fengjie Ma
Spin-orbit coupling (SOC) is incorporated into the phaseless plane-wave-based auxiliary-field quantum Monte Carlo (pw-AFQMC) method. This integration is implemented using optimized…
Strain-triggered high-temperature superconducting transition in two-dimensional carbon allotrope
Tian Yan, Ru Zheng, Jin-Hua Sun +5
Driving non-superconducting materials into a superconducting state through specific modulation is a key focus in the field of superconductivity. Pressure is a powerful method that…
Quantum anomalous Hall effect with high Chern number in two dimensional ferromagnets Ti2TeSO

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…
