AI总结：
针对总填充因子为1且层间严重不平衡的双层量子霍尔系统，本文阐明激子Wigner晶体熔化导致重入超流，并揭示无序下电子—空穴晶体锁定/解耦转变引起逆流电导突变。
摘要：
近期一项输运实验[Zeng2023，arXiv:2306.16995]在严重层间不平衡的区域研究了总填充因子为1的双层量子霍尔系统，并得到了有趣的新发现。本文证明：1）该区域中的激子Wigner晶体可熔化为超流相，从而产生重入超流行为；2）在存在无序时，随着层间距增大，两层中的电子和空穴Wigner晶体会经历锁定/解耦转变，导致逆流电导发生突变。本文还将与实验发现进行比较。
英文摘要：
Bilayer quantum hall system with total filling factor 1 was studied in the regime of heavy layer imbalance in a recent transport experiment [Zeng2023, arXiv:2306.16995], with intriguing new findings. We demonstrate in this paper that 1) the exciton Wigner crystal in this regime can melt into a superfluid phase, giving rise to re-entrant superfluid behavior; 2) in the presence of disorder, electron and hole Wigner crystals in the two layers go through a locking/decoupling transition as layer separation increases, resulting in a sudden change in the counter flow conductance. Comparison will be made with the findings of experiments.
