Abstract
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.
