论文摘要
我们研究复合冷原子系统中的非典型弛豫,由具有负微型典型热的子系统组成。由于单个绝热不变的出现,该系统表现出远离可集成性的远距离热力化。弯曲的不稳定性将组成子系统驱动到其允许能量谱的边缘,从而大大增强了降低降低状态与长时间热结果之间的对比度。
We study non-canonical relaxation in a composite cold atoms system, consisting of subsystems that possess negative microcanonical specific heat. The system exhibits pre-thermalization far away from integrability due to the appearance of a single adiabatic invariant. The Thirring instability drives the constituent subsystems towards the edges of their allowed energy spectrum, thus greatly enhancing the contrast between the prethermal state and the long time thermal outcome.
