SUMMARY:Statistical physics of fluctuations away from equilibrium
DESCRIPTION:Featuring Yariv Kafri\, Technion\nHosted by: Anatoli Polkovniko
	v\n\nPart of the Condensed Matter Theory Seminar Series.\n\nAbstract:\nThe 
	talk will present recent progress in understanding the statistical physics 
	of non-equilibrium diffusive systems. \nFirst\, I will argue that by studyi
	ng the probability of rare events in such systems one is able to probe the 
	direct analog of a free energy in equilibrium systems. Methods for carrying
	 out such calculations will be outlined. Finally\, the analytical structure
	 of the non-equilibrium free energy analogs\, termed large deviation functi
	onals\, will be contrasted with that of equilibrium systems. In particular\
	, it will be shown that 1) out of equilibrium the functionals are generical
	ly non-local functionals of the densities and 2) that in some models the fu
	nctionals exhibit an unusual singular behavior. The singularities are uniqu
	e to non-equilibrium systems and are a direct consequence of the breaking o
	f time-reversal symmetry.
