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…
