SUMMARY:First observation of shock waves in a Unitary Fermi Gas
DESCRIPTION:Featuring Manas Kulkarni\, Stony Brook University\n\nPart of th
	e Condensed Matter Theory Seminar Series.\n\nAbstract:\nWe study non-equili
	brium dynamics in a Unitary Fermi gas in collaboration with Duke. We find t
	hat the collision between two atomic clouds exhibits exotic nonlinear hydro
	dynamics distinguished by the formation of a peak at the center of the trap
	 and subsequent evolution into a box-like shape. This experiment was unders
	tood by using a dimensionally reduced quasi-1D form of the hydrodynamic equ
	ations of motion and we found a near perfect agreement with the experiment.
	 We see a clear evidence of shock wave formation. This is a hallmark of non
	linear physics in a universal quantum hydrodynamic system\, where the inter
	actions are understood and tunable. In addition\, we present non-equilibriu
	m dynamics in another family of interacting quantum system (with invers
	e-square interaction) and we will show that this is very similar to sys
	tems with delta interactions.
