论文摘要
在一维中，量子波动阻止了超固体中的远程顺序，并且只有准远程顺序才能生存。我们得出了这种量子关键行为，并研究了其对固体的超流体反应和特性的影响。该分析基于有效的低能量描述，说明了两种耦合金石模式。我们发现，量子相的量相变为超丝丝，通过量子波动从其平均场预测转移。但是，对于目前具有偶极原子气体的实验参数，这种转移是不可观察的，并且过渡似乎是平均场景。
In one-dimension, quantum fluctuations prevent the appearance of long-range order in a supersolid, and only quasi long-range order can survive. We derive this quantum critical behavior and study its influence on the superfluid response and properties of the solid. The analysis is based on an effective low-energy description accounting for the two coupled Goldstone modes. We find that the quantum phase transition from the superfluid to the supersolid is shifted by quantum fluctuations from its mean-field prediction. However, for current experimental parameters with dipolar atomic gases, this shift is not observable and the transition appears to be mean-field like.
