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…
Effective Field Theory for Superconducting Phase Transitions
Yanyan Bu, Zexin Yang
Employing the Schwinger-Keldysh formalism, we formulate an effective field theory for s-wave superconducting phase transition, where the dynamical variables consist of electromagne…
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…
Universal scalefree non-Hermitian skin effect near the Bloch point
Wei Li, Zhoujian Sun, Ze Yang +1
The scalefree non-Hermitian skin effect (NHSE) refers to the phenomenon that the localization length of skin modes scales proportionally with system size in non-Hermitian systems.…
