Polariton quantum blockade in a photonic dot
We investigate the quantum nonlinear dynamics of a resonantly excited
photonic quantum dot embedding a quantum well in the strong exciton-photon
coupling regime. Within a master equation approach, we study the polariton
quantum blockade and the generation of single photon states due to
polariton-polariton interactions as a function of the photonic dot geometry,
spectral linewidths and energy detuning between quantum well exciton and
confined photon mode. The second order coherence function is
calculated for both continuous wave and pulsed excitations

Quantum Monte Carlo study of ring-shaped polariton parametric luminescence in a semiconductor microcavity
We present a quantum Monte Carlo study of the quantum correlations in the
parametric luminescence from semiconductor microcavities in the strong
exciton-photon coupling regime. As already demonstrated in recent experiments,
a ring-shaped emission is obtained by applying two identical pump beams with
opposite in-plane wavevectors, providing symmetrical signal and idler beams
with opposite in-plane wavevectors on the ring. We study the squeezing of the
signal-idler difference noise across the parametric instability threshold,
accounting for the radiative and non-radiative losses, multiple scattering and
static disorder. We compare the results of the complete multimode Monte Carlo
simulations with a simplified linearized quantum Langevin analytical model
