Quantum Fluctuations and Time Structures of High Density Polaritons

The quantum fluctuations of coherent polaritons in bulk samples are quenched due to the macroscopic occupation number of the single‐particle state. But in the microcrystallites at low levels of excitation antibunching of the quasiparticles can occur. The nonstationary behavior of the coherent polaritons is characterized by the periodic, quasiperiodic, and chaotic self‐pulsations. The phase trajectories are characterized by the limiting cycle, torus or strange attractor.
