Entanglement and non-local magic in a non-unitarily deformed non-Hermitian bipartite system
Chen-Huan Wu
Non-Hermitian degeneracies are usually discussed through spectral coalescence, whereas entanglement is a property of eigenvectors and need not be fixed by the eigenvalues alone. We…
Spectral Mixing, Skin Localization, and Linear Optical Response in Dissipative Photonic Lattices
Chen-Huan Wu
We study the linear optical response of a finite dissipative Hatano--Nelson photonic lattice. The response between selected input and output ports is resolved into a phase-coherent…
Holstein mechanism in single-site model with unitary evolution
Chen-Huan Wu
We investigate the Holstein mechanism in a single-electron (one-site) system, where unitary evolution intrinsically involves both fermion and boson operators under nonadiabatic con…
Local boson-nonlocal boson coupling in a four-level system: Adiabatic, non-adiabatic, and non-Hermitian effects
Chen-Huan Wu
We investigates the dynamics of an open quantum system comprising a two-level electronic system coupled to local boson mode and a bosonic bath. The system is described by four dist…
