Nonreciprocal Quantum Mpemba Effect
Wei-Bin Yan, Ying-Jie Zhang, Yun-Jie Xia +2
We demonstrate a nonreciprocal quantum Mpemba effect. Consider a broad class of open quantum systems, each coupled to two isomorphic reservoirs through symmetric ports. Interchangi…

Qubit coupled with an effective negative-absolute-temperature bath in off-resonant collision model
Wei-Bin Yan, Zhong-Xiao Man, Ying-Jie Zhang +1
Quantum collision model provides a promising tool for investigating system-bath dynamics. Most of the studies on quantum collision models work in the resonant regime. In quantum dy…

Hierarchical environment-assisted dynamical speedup control
Kai Xu, Wei Han, Ying-Jie Zhang +2
We investigate the qubit in the hierarchical environment where the first level is just one lossy cavity while the second level is the N-coupled lossy cavities. In the weak coupling…
