Quantum Correlations in System of Kerr Nonlinear Coupler

We consider a system composed of two linearly mutually interacting, identical Kerr-like nonlinear oscillators. Assuming that the system initially is in a coherent state, we discuss the system's dynamics and concentrate on the field's mutual correlations. As a measure of such correlations, we apply the normalized first- and second-order coherence functions. We derive the analytical formulas for such functions showing that their time-evolution strongly depends on the linear coupling parameter.

Automated summary

The study focuses on a system of two linearly interacting Kerr-like nonlinear oscillators, initially in a coherent state. The system's dynamics and mutual correlations of the field were discussed, using normalized first- and second-order coherence functions as measures. Analytical formulas for these functions were derived, showing a strong dependence on the linear coupling parameter for their time evolution.
