Abstract ritorna |
Due to recent experimental achievements with trapped ultra-cold atoms,
the properties of the 1D non-relativistic Bose gas are of great
interest. In many experimental setups the behaviour of the particles
is very well described by the Lieb-Liniger model which in many aspects
can be regarded as a theoretical benchmark in the research of
integrable models. In spite of its integrability, calculating
correlation functions in the model is notoriously difficult. In the
talk I will propose a novel approach to compute expectation values in
the Lieb-Liniger model. The method is based on the fact that in 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. This observation allows us to compute expectation values in the
Lieb-Liniger system both at zero and finite temperature.
