Violation of Leggett-Garg Inequalities in a Kerr-Type Chaotic System

We consider a quantum nonlinear Kerr-like oscillator externally pumped by a series of ultrashort coherent pulses to analyze the quantum time-correlations appearing while the system evolves. For that purpose, we examine the violation of the Leggett-Garg inequality. We show how the character of such correlations changes when the system's dynamics correspond to the regular and chaotic regions of its classical counterpart.

Automated summary

We investigated the time correlations of a quantum nonlinear Kerr-like oscillator pumped by ultrashort coherent pulses, analyzing the violation of the Leggett-Garg inequality. We observed how these correlations change as the system's dynamics transition between regular and chaotic regions in its classical counterpart.
