论文摘要
超时订购的相关性（OTOC）函数已被用作许多物理系统中量子混乱的指标。在这项工作中，我们在计算上证明了Zerotemperature OTOC可以检测各向异性DICKE模型中的量子相变。使用OTOC给出相图。研究有限尺寸的效果。最后，讨论了温度效应。
Out-of-time-ordered correlation (OTOC) functions have been used as an indicator of quantum chaos in a lot of physical systems. In this work, we computationally demonstrate that zerotemperature OTOC can detect quantum phase transition in anisotropic Dicke model. Phase diagram is given with OTOC. Finite-size effect is studied. Finally, temperature effect is discussed.
