SUMMARY:"A Bosonization Puzzle in Non-linear Transport"
DESCRIPTION:Featuring Carlos Bolech\, University of Cincinnati\n\nPart of t
	he Condensed Matter Theory Seminar Series.\n\nIn this talk\, we will critic
	ally reexamine the bosonization-debosonization procedure for systems includ
	ing localized features or boundaries. First\, by focusing on the case of a 
	tunneling junction out of equilibrium\, we will show that the conventional 
	bosonization approach can give results that are not consistent with a direc
	t solution of the problem even at the qualitative level when higher-order p
	rocesses are considered. Thus highlighting possible inconsistencies that ca
	n adversely affect the results of all types of calculations. We will subseq
	uently report on a "consistent bosonization-debosonization" procedure that 
	we have developed to resolve this non-linear transport puzzle and argue tha
	t it should be widely applicable [1]. This new framework takes the form of 
	additional considerations\, related to the regularization of fermionic bili
	nears\, that supplement the conventional bosonization procedure and it can 
	be carried over to the study of other systems. We will then discuss its app
	lication to the two-lead Kondo junction [2]\, that besides being a key theo
	retical prototype of a non-equilibrium strongly correlated system is also o
	f continuing experimental relevance. The discussion will be focused on the 
	Toulouse limit of that problem.  \n\nReferences:\n[1] Nayana Shah and C. J.
