Free-energy landscape and the critical velocity of superfluid films
We briefly review some important properties of superfluid flow, especially the problem of critical velocity. We then present new numerical simulation results for a... -
Experimental evidence of the statistical intermittency in a cryogenic turbule...
This experimental work is focused on the the statistical study of the high Reynolds number turbulent velocity field in an inertially driven liquid helium... -
Bose-Einstein condensate in a dressed trap: collective modes in a two-dimensi...
This thesis presents the production of a degenerate rubidium 87 gas in the quasi two-dimensional (2D) regime and the study of collective modes of this gas. We show...
