Quantum Anomalous Hall Effect through Canted Antiferromagnetism
Xiao Li, Allan H. MacDonald, Hua Chen
Most canted antiferromagnets are also anomalous Hall antiferromagnets (AHE AFMs), i.e. they have an anomalous Hall response and other responses with the same symmetry requirements.…
Geometric Dynamics of Magnetization: Electronic Contribution
Bangguo Xiong, Hua Chen, Xiao Li +1
To give a general description of the influences of electric fields or currents on magnetization dynamics, we developed a semiclassical theory for the magnetization implicitly coupl…
SU(3) Quantum Hall Ferromagnetism in SnTe
Xiao Li, Fan Zhang, A. H. MacDonald
The (111) surface of SnTe hosts one isotropic -centered and three degenerate anisotropic - centered Dirac surface states. We predict that a nematic phase with spont…
Spontaneous Layer-Pseudospin Domain Walls in Bilayer Graphene
Xiao Li, Fan Zhang, Qian Niu +1
Bilayer graphene is susceptible to a family of unusual broken symmetry states with spin and valley dependent layer polarization. We report on a microscopic study of the domain wall…
Valley Contrasting Magnetoluminescence in Monolayer MoS Quantum Hall Systems
Rui-Lin Chu, Xiao Li, Sanfeng Wu +4
The valley dependent optical selection rules in recently discovered monolayer group-VI transition metal dichalcogenides (TMDs) make possible optical control of valley polarization,…
Unconventional Quantum Hall Effect and Tunable Spin Hall Effect in MoS2 Trilayers
Xiao Li, Fan Zhang, Qian Niu
We analyze the Landau level (LL) structure and spin Hall effect in a MoS2 trilayer. Due to orbital asymmetry, the low-energy Dirac fermions become heavily massive and the LL energi…
