Polarization-induced Quantum Spin Hall Insulator and Topological Devices in InAs Quantum Wells
Chenhao Liang, Sheng Zhang, Haohao Sheng +4
In this work, we predict the emergence of a quantum spin Hall insulator (QSHI) in conventional semiconductors, specifically InAs quantum wells, driven by a built-in polarization fi…

Evidence for an axionic charge density wave in the Weyl semimetal (TaSe4)2I
Johannes Gooth, Barry Bradlyn, Shashank Honnali +9
An axion insulator is a correlated topological phase, predicted to arise from the formation of a charge density wave in a Weyl semimetal. The accompanying sliding mode in the charg…
