2D flow of a strongly interacting Bose-Einstein condensate — •Eder Santana Annibale — Universität Augsburg, Augsburg, Deutschland

The dynamics of a dilute Bose-Einstein condensate (BEC) can be described to a good approximation by the Gross-Pitaevskii equation (GP). On the other hand, the slave-boson model (SB) has been shown very useful to describe a strongly interacting BEC. In this work we study the dynamics (free expansion) of a strongly interacting BEC using the SB model, in particular the generation of shock waves past an obstacle. This problem was considered using the GP, where it was shown the generation of oblique dark solitons and linear waves. Here, we intend to understand the role of the nonlinearity in the SB for the generation of shock waves.
