Nonlinear behaviour of ultracold atoms in optical dipole traps : large atomic light shifts, a quantum phase transition, and interaction-dependent dynamics 

Coop, Simon (Date of defense: 2018-09-06)

This thesis reports on theory and results from two experiments related to nonlinear behaviour in ensembles of optically-trapped ultracold atoms. The first experiment, performed at ICFO in Barcelona, regards the prediction ...
