Dissipation-induced bound states as a two-level system
Hong Peng Zhang, Zhi Song
Potential wells are employed to constrain quantum particles into forming discrete energy levels, acting as artificial few-level systems. In contrast, an anti-parity-time ($\mathcal…

Dynamics of non-Hermitian Floquet Wannier-Stark system
H. P. Zhang, K. L. Zhang, Z. Song
We study the dynamics of the non-Hermitian Floquet Wannier-Stark system in the framework of the tight-binding approximation, where the hopping strength is a periodic function of ti…
