我们通过研究耦合连续时间晶体系综的动力学引入了时间结晶晶种的概念。我们证明，处于对称破缺相的单个子系统作为成核中心可能会导致整个系综的时间平移对称性破缺。观察到相干耦合和耗散耦合以及广泛的参数范围的种子。本着相互同步的精神，我们研究了所有子系统都处于对称破缺阶段的参数状态。我们观察到，更广泛的失谐时间晶体需要更弱的耦合强度才能同步。这与经典和量子同步理论的基础知识形成对比。我们表明，这一令人惊讶的观察结果是种子效应的直接结果。
We introduce the concept of seeding of crystallization in time by studying the dynamics of an ensemble of coupled continuous time crystals. We demonstrate that a single subsystem in a broken-symmetry phase acting as a nucleation center may induce time-translation symmetry breaking across the entire ensemble. Seeding is observed for both coherent and dissipative coupling, as well as for a broad range of parameter regimes. In the spirit of mutual synchronization, we investigate the parameter regime where all subsystems are in the broken-symmetry phase. We observe that more broadly detuned time crystals require weaker coupling strength to be synchronized. This is in contrast to basic knowledge from classical as well as quantum synchronization theory. We show that this surprising observation is a direct consequence of the seeding effect.
