Modulational instability mechanisms in exciton-polariton condensates

The objective of the present paper is to investigate the behaviour of exciton-polariton condensates using the modulational instability mechanism. The study incorporates a complex state that involves quintic order nonlinearity due to polariton energy shift effects, as well as nonlinear dispersion effects. The investigation considers both constant and temporally variable wave numbers and cubic dispersion parameters. The results of the study indicate that various factors, including the physical parameters of the system, wave number, time variability, and construction constants of the field vector, influence the amplitude and configuration of the breather wave function.
