SUMMARY:Non-Equilibrium Transport and Current Imaging in Nanoscopic Quantum
	 Networks
DESCRIPTION:Featuring Dirk Morr\, University of Illinois\, Chicago\n\nPart 
	of the Condensed Matter Theory Seminar Series.\n\nAbstract: Understanding c
	harge transport in nanoscale systems has attracted significant interest ove
	r the last few years in the context of molecular and nano-electronics and t
	hrough advances in the fabrication of artificial quantum structures.  
	The coherent nature of such nanoscopic systems is of particular interest: i
	t leads to the formation of eigenmodes in the density of states\, which pos
	sess distinct spatial patterns and are the basis for the engineering of nov
	el quantum phenomena\, such as quantum imaging.  In this talk\, I will
	 demonstrate that analogous spatial patterns also emerge in the charge tran
	sport through nanoscopic quantum networks in form of current eigenmodes. Th
	ese eigenmodes can be selected through gating or via constrictions\, thus a
	llowing new venues for manipulating charge transport at the nanoscale. More
	over\, I will show how the spatial patterns of current eigenmodes evolve wi
	th dephasing from the ballistic to the classical limit. Finally\, I will de
	monstrate how atomically resolved imaging of spatial current patterns can b
	e obtained using scanning tunneling microscopy.
