我们研究了带有分裂兴奋的三维U（1）旋转液相的有限温度筛选行为。常规U（1）旋转液体共享多个功能。该系统可以在低温下在宏观长度尺度上表现出旋转的液体物理学，但是筛选效应最终导致平滑的有限温度交叉在足够大的距离下变为微不足道的相。但是，与更常规的U（1）自旋液体不同，我们发现分布盆的完整低温筛选不仅需要很大的距离，而且需要很长的时间表。在最长的时间范围内，带电的干扰（分裂）将获得其他分区的筛选云，从而导致系统中的短距离相关性。另一方面，在中间时间尺度上，只能通过移动激发云来部分筛选Fracton，从而在系统中留下弱的幂律相关性。在对U（1）分正面阶段的实验搜索中，这种残留的幂律相关性可能是有用的诊断。
We investigate the finite-temperature screening behavior of three-dimensional U(1) spin liquid phases with fracton excitations. Several features are shared with the conventional U(1) spin liquid. The system can exhibit spin liquid physics over macroscopic length scales at low temperatures, but screening effects eventually lead to a smooth finite-temperature crossover to a trivial phase at sufficiently large distances. However, unlike more conventional U(1) spin liquids, we find that complete low-temperature screening of fractons requires not only very large distances, but also very long timescales. At the longest timescales, a charged disturbance (fracton) will acquire a screening cloud of other fractons, resulting in only short-range correlations in the system. At intermediate timescales, on the other hand, a fracton can only be partially screened by a cloud of mobile excitations, leaving weak power-law correlations in the system. Such residual power-law correlations may be a useful diagnostic in an experimental search for U(1) fracton phases.
