SUMMARY:Novel boundaries for quantum Hall fluids:  The bent quantum Hall ju
	nction
DESCRIPTION:Featuring Matthew Grayson\, Northeastern University\n\nPart of 
	the Biophysics/Condensed Matter Seminar Series.\n\nAbstract: "A growth tech
	nique developed by the author and collaborators produces a two-dimensional 
	electron system bent at 90 degrees with nanometer-scale sharpness.  In the 
	presence of a quantizing magnetic field at varying orientations\, the bound
	ary can host new types of boundaries for quantum Hall systems.  This talk w
	ill present the case of a B-field at 45 degrees to each facet\, whereby a l
	ong corner-junction of counterpropagating quantum Hall edges reconstitutes 
	a wire-like system\, and the case of a B-field at 90 degrees to one facet\,
	 whereby a short corner-junction shows evidence of momentum-resolved coupli
	ng and spectroscopic structure in the quantum Hall edge."
