Abstract

This project aims at investigating the intensity of the emitted far-field by dilute atomic clouds where the light-mediated long-range interaction predominates. Spontaneous emission and interference effects then play an important role, differently from subwavelength systems of Rydberg atoms, yet the multiple scattering of light allows for remote atoms to exhibit correlations. During this internship, the student will address this problem in the quantum optics case of high saturation and compare with experimental results to be obtained in Nice, France. (AU)
