Non-Markovian Exceptional Points by Interpolating Quantum Channels
Wai Chun Wong, Bei Zeng, Jensen Li
Exceptional points (EPs) are special points in non-Hermitian systems where both eigenvalues and eigenvectors coalesce. In open quantum systems, these points are typically analyzed…

Complete Interband Transitions for Non-Hermitian Spin-Orbit-Coupled Cold-Atom Systems
Dong Liu, Zejian Ren, Wai Chun Wong +5
Recently, synthetic spin-orbit coupling has been introduced into cold-atom systems for more flexible control of the Hamiltonian, which was further made time-varying through two-pho…
