SUMMARY:Strongly Correlated Electrons Driven by an Electric Field
DESCRIPTION:Featuring Dr. Camille Aron\, Rutgers University\nHosted by: Cla
	udio Chamon\n\nPart of the Condensed Matter Theory Seminar Series.\n\nAbstr
	act:\nStrongly correlated many-body systems driven out of equilibrium are\n
	attracting a lot of interest\, motivated by new experimental\nrealizations 
	in non-linear transport in devices\, heterostructures and\ncold atoms. Theo
	retically\, the challenge is to understand the\ninterplay between the stron
	g correlation and the finite drive. In this\ntalk\, I will focus on the Hub
	bard model driven by a constant electric\nfield. First\, I will introduce t
	he theoretical tools we used to\naddress the non-equilibrium steady states\
	, bypassing the transient\ndynamics. At the dynamical mean-field level\, I 
	will describe how the\nlattice problem can be self-consistently mapped to a
	 multi-lead\nAnderson impurity model. Afterwards\, I will discuss the fate 
	of Mott\nphysics in the non-linear regime by detailing two key far from\neq
	uilibrium phenomena:\n - the dimensional crossover towards a lower dimensio
	nal equilibrium system;\n - the dielectric breakdown of the Mott insulator.
