Abstract

Time crystals, as temporal analogs of space crystals, manifest as stable and periodic behavior that breaks time translation symmetry. In an open quantum system, many-body interaction subjected to dissipation allows one to develop the time crystalline order in an unprecedented way, as refer to dissipative time crystals. Here we report the observation of multiple time crystals in the continuously driven-dissipative and strongly interacting Rydberg thermal gases, in which continuous time crystals, sub-harmonic time crystals and high-harmonic time crystals are observed in the same system by manipulating the Rydberg excitation. Our work provides new ways to explore the non-equilibrium phases of matter in open systems. Such time crystals with persistent oscillation rooted in emergent quantum correlations, may emerge as a ubiquitous tool in quantum metrology, for instance, continuous sensing and parameter estimation surpassing the standard quantum limit.

里德伯气体驱动耗散系统中多时间晶体的观察。

时间晶体作为空间晶体的时间类似物，表现为打破时间平移对称性的稳定和周期性行为。在开放量子系统中，受耗散影响的多体相互作用允许人们以前所未有的方式发展时间晶体秩序，如耗散时间晶体。本文报道了在连续驱动耗散和强相互作用的里德伯热气体中观察到的多时间晶体，其中通过操纵里德伯激发在同一系统中观察到连续时间晶体、次谐波时间晶体和高谐波时间晶体。我们的工作为探索开放系统中物质的非平衡相提供了新的途径。这种基于涌现量子相关的持续振荡的时间晶体，可能会成为量子计量学中无处不在的工具，例如，超越标准量子极限的连续传感和参数估计。
