The applied Boltzmann relaxation kinetics for stationary and ps-pulsed nonresonant pumping takes the polariton–acoustic phonon and the polariton–polariton scattering into account. For cavities with a vacuum Rabi splitting around Ω = 8 meV , we find for ps-pulse excitation a transient bosonic condensation in the ground state. For microcavities with a large vacuum Rabi splitting of Ω = 26 meV we find for zero detuning, due to the steep increase of radiative losses, a condensation with a macroscopically occupied state in the wavenumber region at which the Bragg mirrors become transparent. With positive detunings which increase the scattering rates, the finite-size Bose–Einstein condensation in the ground state is restored. |
