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…

Anomalous heat flow and quantum Otto cycle with indefinite causal order
Qing-Feng Xue, Qi Zhang, Xu-Cai Zhuang +5
The principle that heat spontaneously flows from higher temperature to lower temperature is a cornerstone of classical thermodynamics, often assumed to be independent of the sequen…

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…
