Superradiance as single scattering embedded in an effective medium
P. Weiss, A. Cipris, R. Kaiser +2
We present an optical picture of linear-optics superradiance, based on a single scattering event embedded in a dispersive effective medium composed by the other atoms. This linear-…
Photon thermalization and a condensation phase transition in an electrically pumped semiconductor microresonat
S. Barland, P. Azam, G. L. Lippi +2
We report on an experimental study of photon thermalization and condensation in a semiconductor microresonator in the weak-coupling regime. We measure the dispersion relation of li…
Roles of cooperative effects and disorder in photon localization: The case of a vector radiation field
L. Bellando, A. Gero, E. Akkermans +1
We numerically study photon escape rates from three-dimensional atomic gases and investigate the respective roles of cooperative effects and disorder in photon localization, while…
Cooperative effects and disorder: A scaling analysis of the spectrum of the effective atomic Hamiltonian
L. Bellando, A. Gero, E. Akkermans +1
We study numerically the spectrum of the non-Hermitian effective Hamiltonian that describes the dipolar interaction of a gas of atoms with the radiation field. We analyze…
Low and high intensity velocity selective coherent population trapping in a two-level system
David Wilkowski, Maryvonne Chalony, Robin Kaiser +1
An experimental investigation is made of sub-recoil cooling by velocity selective coherent population trapping in a two-level system in Sr. The experiment is carried out using the…
Hanle effect in coherent backscattering
G. Labeyrie, C. Miniatura, C. A. Mueller +3
We study the shape of the coherent backscattering (CBS) cone obtained when resonant light illuminates a thick cloud of laser-cooled rubidium atoms in presence of a homogenous magne…
