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

Paolo Schwendimann, Antonio Quattropani

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 ...

Higher order coherence of exciton-polariton condensates

Paolo Schwendimann, Antonio Quattropani

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 ...

Stationary and time-dependent correlations in polariton condensates

Paolo Schwendimann, Antonio Quattropani, 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 ...

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

Paolo Schwendimann, Antonio Quattropani, 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 ...

Statistics of the polariton condensate

Paolo Schwendimann, Antonio Quattropani

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 ...

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 ...

Coherence versus Coulomb scattering in resonantly excited quantum wells

Vincenzo Savona, Paolo Schwendimann, Cristiano Ciuti

The role of Coulomb scattering is studied in the coherent transients of strongly driven exciton resonances in semiconductor quantum wells. Coulomb scattering is treated within the second Born approximation and the light-induced dressing of the electron-hol ...

The nonequilibrium dynamics of a two-dimensional electron-hole gas is studied in the regime of strong and resonant pumping of the exciton resonance. The Coulomb collision rates are consistently determined by taking into account the light-induced coherence ...

We derive the effective Bose Hamiltonian for a system of interacting excitons applying the Usui transformation. The fermionic nonlinearities are consistently included, leading to a density dependent correction to the kinetic Hamiltonian and to a saturation ...

Giant angle-resonant polariton amplification

Benoît Marie Joseph Deveaud, Paolo Schwendimann, Cristiano Ciuti

We discuss recent theoretical results on the polariton parametric amplification from semiconductor microcavities in the strong exciton-photon coupling regime. A microscopic treatment of the interacting polariton system leads to a clear description of the p ...
