Unavoidability of nonclassicality loss in -symmetric systems
We show that the loss of nonclassicality (including quantum entanglement) cannot be
compensated by the (incoherent) amplification of PT-symmetric systems. We address this …

Liouvillian exceptional points of an open driven two-level system
N Seshadri, A Li, M Galperin - The Journal of Chemical Physics, 2024 - pubs.aip.org
We study the applicability of the Liouvillian exceptional points (LEPs) approach to nanoscale
open quantum systems. A generic model of the driven two-level system in a thermal …

Exceptional point in self-consistent Markovian master equations
D Xie, C Xu - Physical Review A, 2023 - APS
The cxceptional point (EP) denotes the non-Hermitian degeneracy, in which both
eigenvalues and eigenstates become identical. By the conventional local Markovian master …
