SUMMARY:1D Bose gas as the non-relativistic limit of the sinh-Gordon model 
DESCRIPTION:Featuring Marton Kormos\, SISSA\, Italy\n\nPart of the Condense
	d Matter Theory Seminar Series.\n\nAbstract:\nDue to recent experimental ac
	hievements with trapped ultracold atoms\, the properties of the 1D non-rela
	tivistic Bose gas are of great interest. In many experimental setups the be
	havior of the particles is very well described by the Lieb-Liniger model wh
	ich in many aspects can be regarded as a theoretical benchmark in the resea
	rch of integrable models. In spite of its integrability\, calculating corre
	lation functions in the model is notoriously difficult. In the talk I will 
	propose a novel approach to compute expectation values and other physical q
	uantities in the Lieb-Liniger model. The method is based on the fact that i
	n the repulsive case the S-matrix\, the Lagrangian and the operators can be
	 obtained from a certain non-relativistic limit of the sinh-Gordon model. T
	his observation allows us to compute expectation values in the Lieb-Liniger
	 system both at zero and finite temperature.
