论文摘要
我们引入了超速分子或rydberg原子 - 合成维度的量子物质的经典类似物，扩展了POTTS模型，以在真实和合成空间中附近的原子之间包括相互作用J1并研究其有限温度性能。对于J1的中间值，所产生的阶段和相图与时钟和小人模型的相似，其中三个阶段出现。存在类似于高温无序相和低温铁磁相之间量子合成维度模型的板相。我们还使用机器学习来使用混乱方法学习相图的非平凡特征。该方法的关键结果能够辨别出几个连续的相变。
We introduce a classical analog of quantum matter in ultracold molecule -- or Rydberg atom -- synthetic dimensions, extending the Potts model to include interactions J1 between atoms adjacent in both real and synthetic space and studying its finite temperature properties. For intermediate values of J1, the resulting phases and phase diagrams are similar to those of the clock and Villain models, in which three phases emerge. There exists a sheet phase analogous to that found in quantum synthetic dimension models between the high temperature disordered phase and the low temperature ferromagnetic phase. We also employ machine learning to uncover non-trivial features of the phase diagram using the learning by confusion approach. The key result there is that the method is able to discern several successive phase transitions.
