摘要

我们使用几种技术来探测Das， Das和Mandal提出的用于描述A相的波函数[；;]。与表示分数量子霍尔液体相反，我们发现这些波函数可以描述清楚地显示强相分离的状态。在探索这些波函数的过程中，我们还构建了几种诊断相分离和数值生成相分离波函数的方法。最后，我们揭示了纠缠谱的一个特性，可以用来检查数值的准确性。2025年由美国物理学会出版

Phase separation in the putative fractional quantum Hall A phases

We use several techniques to probe the wave functions proposed to describe the A phases by Das, Das, and Mandal [; ; ]. As opposed to representing fractional quantum Hall liquids, we find these wave functions to describe states that clearly display strong phase separation. In the process of exploring these wave functions, we have also constructed several methods for diagnosing phase separation and generating such wave functions numerically. Finally, we uncover a property of entanglement spectra that can be used as a check for the accuracy of numerics.
