Séminaire de Robin Kaiser le 12 décembre 2023 à 14h00 - Auditorium

Séminaire de Robin Kaiser, directeur de recherche du CNRS au laboratoire Inphyni à Nice, le 12 décembre 2023 à 14h00 dans l'Auditorium de l'Institut d'Optique Graduate School à Palaiseau, sur le thème : " With dipole-dipole interactions towards Anderson localisation. "

Résumé : " The quest for Anderson localization of light is at the center of many experimental and theoretical activities. Cold atoms have emerged as interesting quantum system to study coherent transport properties of light. Initial experiments have established that dilute samples with large optical thickness allow studying weak localization of light, which has been well described by a mesoscopic model. Recent experiments on light scattering with cold atoms have shown that Dicke super- or subradiance occurs in the same samples, a feature not captured by the traditional mesoscopic models. The use of a long range microscopic coupled dipole model allows to capture both the mesoscopic features of light scattering and Dicke super- and subradiance in the single photon limit. I will review experimental and theoretical state of the art on the possibility of Anderson localization of light by cold atoms. "
