SUMMARY:Quantum fluctuations and uncertainty relations in NLS solitons and 
	breathers
DESCRIPTION:Featuring Oleksandr Marchukov\, Tel Aviv University and UMASS B
	oston\nHosted by: Anatoli Polkovnikov\n\nPart of the Biophysics/Condensed M
	atter Seminar Series.\n\nWe consider the quantum fluctuations of the macros
	copic variables associated with a breather\, \na second-order soliton solut
	ion of nonlinear Schrödinger equation. Linearizing the evolution \nof the 
	bosonic quantum field around the Bose condensate in a breather state\,\nwe 
	express the quantum fluctuations of the macroscopic variables through the f
	luctuations \nof the full quantum field. We evaluate the initial quantum un
	certainties of the macroscopic parameters and\ntheir time evolution. We fin
	ally describe how the macroscopic fluctuations affect the time evolution of
	 the \natomic density and estimate the propagation time needed for  an expe
	rimental detection of the predicted effects.
