Quantum Oscillation of Thermally Activated Conductivity in a Monolayer WTe-like Excitonic Insulator
Wen-Yu He, Patrick A. Lee
Recently, quantum oscillation of the resistance in insulating monolayer WTe was reported. An explanation in terms of gap modulation in the hybridized Landau levels of an excito…
Superconducting Orbital Magnetoelectric Effect and its Evolution across the Superconductivity Normal Metal Phase Transition
Wen-Yu He, K. T. Law
Superconducting magnetoelectric effect, which is the current-induced magnetization in a superconductor, mainly focused on the spin magnetization in previous studies, but ignore the…
Giant Orbital Magneto-electric effect and Current-driven Magnetization Switching in Twisted Bilayer Graphene
Wen-Yu He, David Goldhaber-Gordon, K. T. Law
Recently, signatures of quantum anomalous Hall states with spontaneous ferromagnetism were observed in twisted bilayer graphenes (TBGs) near 3/4 filling [1, 2]. Importantly, it was…
Kramers Weyl Semimetals as Quantum Solenoids and Their Applications in Spin-Orbit Torque Devices
Wen-Yu He, Xiao Yan Xu, K. T. Law
Kramers Weyl semimetals are Weyl semimetals that have Weyl points pinned at the time reversal invariant momenta. Recently it has been discovered that all chiral crystals host Weyl…
The Coexistence of van Hove Singularities and Superlattice Dirac Points in a Slightly Twisted Graphene Bilayer
Zhao-Dong Chu, Wen-Yu He, Lin He
We consider the electronic structure of a slightly twisted graphene bilayer and show the coexistence of van Hove singularities (VHSs) and superlattice Dirac points in a continuum a…
