Squeezing and Entanglement Dynamics in Phase-Sensitive Non-Hermitian Systems
Ruicong Huang, Wencong Wang, Yuyang Liang +2
Over the past decade, parity-time (PT) symmetry and anti-PT (APT) symmetry in various physical systems have been extensively studied, leading to significant experimental and theore…
