Experimental Realization of a Nonreciprocal Quantum Battery
Jie Zhang, Xin-Sheng Chen, Ruo Kun Cai +9
Quantum batteries promise faster and more efficient energy storage and extraction by harnessing quantum mechanics, serving as essential building blocks for future quantum devices.…
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…
