Quantum Anomalous Hall Effect in Graphene Proximity Coupled to an Antiferromagnetic Insulator
Zhenhua Qiao, Wei Ren, Hua Chen +4
We propose realizing the quantum anomalous Hall effect by proximity coupling graphene to an antiferromagnetic insulator that provides both broken time-reversal symmetry and spin-or…
Geometrical effects in orbital magnetic susceptibility
Yang Gao, Shengyuan A. Yang, Qian Niu
Within the wave-packet semiclassical approach, the Bloch electron energy is derived to second order in the magnetic field and classified into gauge-invariant terms with clear physi…
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…
Spin pumping and spin-transfer torques in antiferromagnets
Ran Cheng, Jiang Xiao, Qian Niu +1
Spin pumping and spin-transfer torques are two reciprocal phenomena widely studied in ferromagnetic materials. However, pumping from antiferromagnets and its relation to current-in…
Unbalanced edge modes and topological phase transition in gated trilayer graphene
Xiao Li, Zhenhua Qiao, Jeil Jung +1
Gapless edge modes hosted by chirally-stacked trilayer graphene display unique features when a bulk gap is opened by applying an interlayer potential difference. We show that trila…
