论文摘要
受高频驱动的多体系统可以显示出有趣的热化行为。在加热到无特征的无限温度状态之前，这些系统可以在以各种秩序为特征的细头阶段上花费成倍长的时间。在这里，我们揭示了具有竞争性的短距离铁磁和远距离双极相互作用的驱动式挫折二维ISING磁铁的富含非平衡相图。我们表明，有序条带和列阶段以温度的函数出现在平衡中，在新的多步加热过程中以随后的prethermal阶段为基础，在朝着最终的热死亡途中。我们讨论对挫折磁铁中铁磁薄膜和其他驱动诱发现象的实验的含义。
Many-body systems subject to a high-frequency drive can show intriguing thermalization behavior. Prior to heating to a featureless infinite-temperature state, these systems can spend an exponentially long time in prethermal phases characterized by various kinds of order. Here, we uncover the rich non-equilibrium phase diagram of a driven frustrated two-dimensional Ising magnet with competing short-range ferromagnetic and long-range dipolar interactions. We show that the ordered stripe and nematic phases, which appear in equilibrium as a function of temperature, underpin subsequent prethermal phases in a new multi-step heating process en route towards the ultimate heat death. We discuss implications for experiments on ferromagnetic thin films and other driving induced phenomena in frustrated magnets.
