“…With an increase in the normalized resonance detuning α, the region of occurrence of the phenomenon of self-trapping in the system of quasiparticles shifts to the region of higher normalized densities of polaritons of the idle mode. Here, the manifestation of the phenomenon of self-trapping is not as bright as in the case of taking into account the elastic interatomic interaction under the conditions of Bose-Einstein condensation of atoms and molecules [34,35].…”

The dynamics of exciton-polariton states in a semiconductor microcavity is studied under pumping of the state corresponding to the lower polariton branch, taking into account single-mode and intermode elastic polariton-polariton interactions. In this case, pumping is carried out by two laser pulses with close frequencies. It is shown that at the initial phase difference equal to theta0=π/2, the regime of quantum self-trapping of exciton-polaritons is observed. Periodic and aperiodic modes of evolution of a system of quasiparticles are obtained. Keywords: exciton-polariton states, quantum self-trapping, periodic and apeiodic regimes.

“…При увеличении нормированной расстройки резонанса α область возникновения явления самозахвата в системе квазичастиц смещается в область более высоких нормированных плотностей поляритонов холостой моды. Здесь проявление явления самозахвата не столь яркое, как в случае учета упругого межатомного взаимодействия в условиях бозе-эйнштейновской конденсации атомов и молекул [34,35].…”
