Quasi-Non-Hermitian Edge Bursts Induced by Nonuniform Loss
Ze Yang, Wei Li, Fuxiang Li
Non-Hermitian quantum walks on lossy lattices with open boundaries can exhibit an anomalous peak of the loss probability at the boundary, known as the non-Hermitian edge burst (NHE…
Electron-transverse acoustic phonon couplings in three-dimensional pentatellurides
Rui Min, Fuxiang Li, Yi-Xiang Wang
Transverse acoustic (TA) phonon waves are analogous to electromagnetic waves and can carry a certain angular momentum. In this paper, we study the electron-TA phonon couplings in t…
Magnetotransport and activation energy of the surface states in Cd3As2 thin films
Zhigang Cai, Fuxiang Li, Yi-Xiang Wang
Recent experiments performed the magnetotransport measurements in (001)-oriented CdAs thin films and attributed the magnetotransport properties to the surface states. In th…
Loop unitary and phase band topological invariant in generic multi-band Chern insulators
Xi Wu, Ze Yang, Fuxiang Li
Quench dynamics of topological phases have been studied in the past few years and dynamical topological invariants are formulated in different ways. Yet most of these invariants ar…
