Perfect Bound States and non-Markovian Dynamics for Imperfect Giant Atoms in a Semi-Infinite Waveguide
T. Y. Liu, X. Y. Li, W. Y. Hu +3
Bound states in structured reservoirs require exact interference conditions and are therefore sensitive to imperfections in the coupling geometry. In this paper, we study a two-lev…

Quantum Battery Enhancement via Degenerate Optical Parametric Amplifier and Common Reservoirs
Y. Y. Yang, H. N. Liu, Gangcheng Wang +2
We investigate a nonreciprocal quantum battery in which the charger and battery share one or two common reservoirs, with the charger driven by a degenerate optical parametric ampli…
