Universal Entanglement Revival of Topological Origin
Dongni Chen, Stefano Chesi, Mahn-Soo Choi
We have analyzed the dynamics of entanglement in dissipative fermionic and bosonic Su-Schrieffer-Heeger (SSH) models and found that, when the decoherence channel preserves the chir…
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…
Self-Purification and Entanglement Revival in Lambda Matter
Dongni Chen, Stefano Chesi, Mahn-Soo Choi
In this study, we explore the dynamics of entanglement in an ensemble of three-level systems with a lambda-type level structure interacting with single-mode bosons. Our investigati…
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…
