Out-of-time-order correlations and Floquet dynamical quantum phase transition
Out-of-time-order correlations and Floquet dynamical quantum phase transition
Out-of-time-order correlators (OTOCs) progressively play an important role in different fields of physics, particularly in the nonequilibrium quantum many-body systems. In this paper, we show that OTOCs can be used to probe the Floquet dynamical quantum phase transitions (FDQPTs). We investigate the OTOCs of two exactly solvable Floquet spin models, …
