摘要:
我们证明开放量子系统中表现出动态相变(DPTs)的现象允许高效协议实现Pontus-Mpemba效应。向预定目标态的弛豫加速与长暂稳时间窗口 preceding DPT 的存在有关,可以在应用中系统地优化量子协议。作为DPTs与量子Mpemba效应联系的典范例子,我们研究了一维(1D)相互作用费米子系统,对应于耗散型的Gross-Neveu(GN)模型变体。
英文摘要:
We demonstrate that open quantum systems exhibiting dynamical phase transitions (DPTs) allow for efficient protocols implementing the Pontus-Mpemba effect. The relaxation speed-up toward a predesignated target state is tied to the existence of a long metastable time window preceding the DPT and can be exploited in applications to systematically optimize quantum protocols. As paradigmatic example for the connection between DPTs and quantum Mpemba effects, we study one-dimensional (1D) interacting lattice fermions corresponding to a dissipative variant of the Gross-Neveu (GN) model.
