论文摘要
离散的时间晶体是定期驱动的系统，以无限期亚谐波振荡的形式显示时间翻译不变性的自发对称性破坏。我们引入了一个热力学一致的模型，以用于离散时间晶体，并使用随机热力学的框架进行分析。特别是，我们评估了这种与热浴接触的嘈杂的噪声亚谐波振荡器相互作用的体系系统的能量耗散速率。我们的模型显示了亚谐波同步的新现象，该现象与单个单位的集体亚谐波振荡相对应。
Discrete time crystals are periodically driven systems that display spontaneous symmetry breaking of time translation invariance in the form of indefinite subharmonic oscillations. We introduce a thermodynamically consistent model for a discrete time crystal and analyze it using the framework of stochastic thermodynamics. In particular, we evaluate the rate of energy dissipation of this many body system of interacting noisy subharmonic oscillators in contact with a heat bath. Our model displays the novel phenomena of subharmonic synchronization, which corresponds to collective subharmonic oscillations of the individual units.
