Theory of anomalous Landau-Zener tunneling induced by nonlinear coupling
Wen-Yuan Wang, Hong-Juan Meng
We develop a general theory of Landau-Zener (LZ) tunneling in a two-level system with amplitude-dependent, sign-reversible nonlinear coupling, distinguishing it fundamentally from…
Ergotropy in Quantum Batteries
Cheng-Jie Wang, Fu-Quan Dou
Ergotropy--a key figure of merit for quantum battery (QB) performance--plays a crucial role. However, the dynamics and physical mechanisms governing ergotropy evolution remain open…
Cyclotron dynamics of a Bose-Einstein condensate in a quadruple-well potential with synthetic gauge fields
Wen-Yuan Wang, Ji Lin, Jie Liu
We investigate the cyclotron dynamics of Bose-Einstein condensate (BEC) in a quadruple-well potential with synthetic gauge fields. We use laser-assisted tunneling to generate large…
Quantum battery of interacting spins with environmental noise
Fang Zhao, Fu-Quan Dou, Qing Zhao
A quantum battery is a temporary energy-storage system. We constructed the quantum battery model of an N-spin chain with nearest-neighbor hopping interaction and investigated the c…
