We prove the existence of non-equilibrium phases of matter in the prethermal regime of periodically-driven, long-range interacting systems, with power-law exponent α>d, where d is the dimensionality of the system. In this context, we predict the existence of a disorder-free, prethermal discrete time crystal in one dimension—a phase strictly forbidden in the absence of long-range interactions. Finally, using a combination of analytic and numerical methods, we highlight key experimentally observable differences between such a prethermal time crystal and its many-body localized counterpart.

非平衡物质的长期预热相

我们证明了周期性驱动的长距离相互作用系统的预热态中物质的非平衡相的存在,并且具有幂律指数 α>d, 在哪里 d是系统的维数。在这种情况下,我们预测了一维无序,预热的离散时间晶体的存在-在没有长距离相互作用的情况下严格禁止该相。最后,结合分析和数值方法,我们强调了这种预热时间晶体与其多体局部对应物之间在实验上可观察到的关键差异。
