Thouless pumping and generation of squeezed Fock-state superpositions in a Fock-state lattice
Ruo Kun Cai, Ling Lin, Chun Wang Wu +2
In this paper, Thouless pumping in a one-dimensional semi-infinite Fock-state lattice is investigated. A distinctive feature of such lattices is the intrinsic -dependent…

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…
