Discovery of d-orbital order in Tb2CoAl4Ge2
Zhanyang Hao, Haohao Sheng, Wanru Ma +32
Orbital order describes a quantum state where occupied orbitals line up in a periodic pattern. While orbital physics plays a fundamental and universal role in strongly correlated e…

Symmetry-Indicated Time-Reversal-Doubled Axion Insulators
Yue Xie, Haohao Sheng, Quansheng Wu +4
The axion insulator exhibits a topological magnetoelectric effect characterized by an axion angle , while the time-reversal-doubled axion insulator (T-DAXI) can be viewed as…

Majorana Zero Modes and Topological Nature in Bi2Ta3S6-family Superconductors
Yue Xie, Zhilong Yang, Ruihan Zhang +7
In this work, we report that Bi2Ta3S6-family superconductors exhibit nontrivial band topology. They possess a natural quantum-well structure consisting of alternating stacks of TaS…
