Optimized generation of entanglement based on the f-STIRAP technique
Dongni Chen, Jiahui Li, Stefano Chesi +1
We consider generating maximally entangled states (Bell states) between two qubits coupled to a common bosonic mode, based on f-STIRAP. Utilizing the systematic approach developed…
Spin fluctuations in the dissipative phase transitions of the quantum Rabi model
Jiahui Li, Rosario Fazio, Yingdan Wang +1
We investigate the dissipative phase transitions of the anisotropic quantum Rabi model with cavity decay and demonstrate that large spin fluctuations persist in the stationary stat…
Nonlinear dynamics in the balanced two-photon Dicke model with qubit dissipation
Jiahui Li, Stefano Chesi
We study the complex nonlinear dynamics of the two-photon Dicke model in the semiclassical limit by considering cavity and qubit dissipation. In addition to the normal and super-ra…
Discrete time crystal in an open optomechanical system
Dongni Chen, Zhengyang Peng, Jiahui Li +2
The spontaneous breaking of time translation symmetry in periodically driven Floquet systems can lead to a discrete time crystal. Here we study the occurrence of such dynamical pha…
