Quantum-Optical Bound States in the Continuum
Ruo Kun Cai, Zhi Jiao Deng, Chun Wang Wu +1
Bound states in the continuum (BICs) are counterintuitive localized states that lie within the continuum of extended states. While extensively realized and utilized in classical wa…

Confined non-Hermitian skin effect in a semi-infinite Fock-state lattice
Zhi Jiao Deng, Xing Yao Mi, Ruo Kun Cai +2
In this paper, we investigate the non-Hermitian skin effect in a semi-infinite Fock-state lattice, where the inherent coupling scales as \sqrt{n}. By analytically solving a non-uni…

Magnonic entanglement in a chiral cavity-magnon coupling system
Yuxin Kang, Xin Zeng, Wuji Zhang +3
The generation of magnon entanglement and squeezing plays a crucial role in quantum information processing. In this study, we propose a scheme based on a chiral cavity-magnon syste…
