Abstract

This project at showing how ultracold atomic clouds may turncoherent light into a chaotic one, even in absence of motion and ofinteractions: The resonance fluorescence, which reflects the broadening of theemission when the atoms are saturated, leads to a 'randomization' of thephase of the emitted wave. As a witness of the chaotization of the emittedwave, the Siegert relation, which relates field-field and intensity-intensitycorrelations, will be monitored. In the last phase of the project, the student willstudy the role of the interactions.
