Berry curvature effects of chiral superconducting rhombohedral graphene
Jian-Hua Zeng, Zhi Wang, Qian Niu
We study the Berry curvature effects of the Bogoliubov quasiparticles in chiral superconducting rhombohedral graphene. Using a two-band Bogoliubov-de Gennes Hamiltonian to describe…
Surface Originated Cross-Field Anomalous Transport in Magnetoelectric Multilayers
Jin Cao, Wei Du, Xue-Jin Zhang +3
In material systems with slab geometry, the surface contribution to physical responses is commonly expected to diminish rapidly with increasing thickness, giving way to the bulk re…
Semiclassical theory for the orbital magnetic moment of superconducting quasiparticles
Jian-Hua Zeng, Jian-hua Zeng, Zhongbo Yan +2
We study the orbital magnetic moment of Bogoliubov quasiparticles in superconductors with the semiclassical approach. We derive the orbital magnetic moment of a quasiparticle wavep…
Semiclassical theory for proximity-induced superconducting systems with spin-orbit coupling
Zhen-Cheng Liao, Cong Xiao, Zhi Wang +1
We develop a semiclassical theory of superconducting quasiparticles for proximity-induced superconducting systems, where spin-orbit coupling plays a critical role in shaping the qu…
Berry Curvature Induced Spin Nernst and Thermal Edelstein Effects in Proximity Superconductors
Zhen-Cheng Liao, Cong Xiao, Zhi Wang +1
We propose two thermo-spintronic responses in proximity induced superconductors with spin-orbit coupled band - spin Nernst effect and thermal Edelstein effect stemming respectively…
Proper Definition of Intrinsic Nonlinear Current
Cong Xiao, Jin Cao, Qian Niu +1
We show that the three commonly employed approaches that define the same dc (or low-frequency) intrinsic linear anomalous Hall response actually lead to different results for intri…
