Abstract
We discuss and model an experiment to study quasi-condensate growth on an atom chip. In particular, we consider the addition of a deep dimple to the weak harmonic trap confining an ultracold one-dimensional atomic Bose gas, below or close to the characteristic temperature for quasi-condensate formation. The subsequent dynamics depends critically on both the initial conditions, and the form of the perturbing potential. In general, the dynamics features a combination of shock-wave propagation in the quasi-condensate, and quasi-condensate growth from the surrounding thermal cloud.
