The Phenomenon of Self-Capture in the Exciton–Polariton System when Pumping the Lower Polariton Branch with Two Laser Pulses with Close Frequencies

The dynamics of exciton–polariton states in a semiconductor microresonator has been studied when pumping the state corresponding to the lower polariton branch considering single-mode and intermode elastic polariton–polariton interactions. In this case, the pumping has been carried out by two laser pulses with close frequencies. It has been shown that at the initial phase difference equal to \({{\theta }_{0}} = \pi {\text{/2}}\), the mode of quantum self-capture of exciton–polaritons is observed. The periodic and aperiodic modes of evolution of a system of quasiparticles have been obtained.
