我们证明，浸没在玻色-爱因斯坦凝聚态中的唐克斯-吉拉多（TG）气体可以转变为类晶体莫特态，原子之间的间距规则，而无需任何外部施加的晶格势。我们将这种相变描述为热重气体的种间相互作用和温度的函数，并展示了如何通过冷原子实验中可观测的可观测值来测量它。我们还开发了一个有效的模型，可以准确地描述处于钉扎绝缘体状态的系统，并使我们能够得出转变的临界温度。
We show that a Tonks-Girardeau (TG) gas that is immersed in a Bose-Einstein condensate can undergo a transition to a crystal-like Mott state with regular spacing between the atoms without any externally imposed lattice potential. We characterize this phase transition as a function of the interspecies interaction and temperature of the TG gas, and show how it can be measured via accessible observables in cold atom experiments. We also develop an effective model that accurately describes the system in the pinned insulator state and which allows us to derive the critical temperature of the transition.
