Dominance of extrinsic scattering mechanisms in the orbital Hall effect: graphene, transition metal dichalcogenides and topological antiferromagnets
Hong Liu, Dimitrie Culcer
The theory of the orbital Hall effect (OHE), a transverse flow of orbital angular momentum in response to an electric field, has concentrated overwhelmingly on intrinsic mechanisms…
Topological nature of the proper spin current and the spin-Hall torque
Hong Liu, James H. Cullen, Dimitrie Culcer
Spin currents are key to spin torque devices, but determining the proper spin current is non-trivial. Here we derive a general quantum-mechanical formula for the intrinsic proper s…
Coherent backscattering in the topological Hall effect
Hong Liu, Rhonald Burgos Atencia, Nikhil Medhekar +1
The mutual interplay between electron transport and magnetism has attracted considerable attention in recent years, primarily motivated by strategies to manipulate magnetic degrees…
Hybrid dark excitons in monolayer
Hong Liu, Anny Pau, Dmitry K. Efimkin
Transition metal dichalcogenides have a rich exciton landscape consisting of a variety of bright and dark excitonic states. We consider the lowest-energy dark states in $\hbox{MoS}…
Anomalous drag in electron-hole condensates with granulated order
Hong Liu, Allan H. MacDonald, Dmitry K. Efimkin
We explain the strong interlayer drag resistance observed at low temperatures in bilayer electron-hole systems in terms of an interplay between local electron-hole-pair condensatio…
Phase diagram of the interacting persistent spin-helix state
Hong Liu, Weizhe Edward Liu, Stefano Chesi +2
We study the phase diagram of the interacting two-dimensional electron gas (2DEG) with equal Rashba and Dresselhaus spin-orbit coupling, which for weak coupling gives rise to the w…
