Quantum-statistical properties of the emission from two-level atoms embedded in coupled cavities

The quantum-statistical properties of the radiation emitted from two coupled cavities containing one or two two-level atoms are discussed, and both configurations are compared. The results concerning stationary photon statistics, photon blocking, squeezing ...

Stationary and time-dependent correlations in polariton condensates

Antonio Quattropani, Paolo Schwendimann, Davide Sarchi

The statistics of the condensed polaritons is described in terms of the Wigner function. In the framework of the truncated Wigner method, the Wigner function obeys a Fokker-Planck equation, which is solved analytically. The second-order correlations in the ...

Higher order coherence of exciton-polariton condensates

Antonio Quattropani, Paolo Schwendimann

The second- and third-order coherence functions g((n))(0) (n= 2 and 3) of an exciton-polariton condensate are measured and compared to the theory. Contrary to an ideal photon laser, deviation from unity in the second- and third-order coherence functions is ...

Statistics of the polariton condensate

Antonio Quattropani, Paolo Schwendimann

The influence of polariton-polariton scattering on the statistics of the polariton condensate in a nonresonantly excited semiconductor microcavity is discussed. Taking advantage of the existence of a bottleneck in the exciton-polariton dispersion curve, th ...

Effects of noise in different approaches for the statistics of polariton condensates

Antonio Quattropani, Paolo Schwendimann, Davide Sarchi

The second-order correlation function of the polariton condensate is calculated within two different approaches. Both approaches qualitatively reproduce the deviations from the full coherence of the second-order correlation function that have been observed ...

Onset of coherent photoluminescence in semiconductor microcavities

Vincenzo Savona, Paolo Schwendimann

The nonlinear dynamics of exciton-polaritons in semiconductor microcavities is treated within a model of interacting bosons for the signal, pump, and idler modes. The correlations between all three polariton modes are taken into account in the lowest order ...
