Abstract
This work examines the growth of a Bose-Einstein condensate in a trapped ultracold bosonic gas quenched across the phase transition. The validity of the Kibble-Zurek framework in the early stages of the symmetry-breaking dynamics is assessed, clarifying the role of different time and spatial scales in the quench and filling in the gap between the early evolution and the corresponding long-time evolution observed in the experiments.
