Title: Attractive Bosons from Bethe Ansatz point of view

10am, Thursday 18^th May, 2006

Priestley Blding, room 140

Abstract:

In recent years experiments on ultracold, quasi one-dimensional quantum gases found interesting new physics. Already about 40 years ago the exact Bethe Ansatz solutions for interacting boson and fermion models in one dimenion were discovered. It soon turned out that the repulsive case was, compared  to the attractive case, theoretically much easier to handle. Concentrating almost entirely on the repulsive regime in the limit of large system size might have kept us from studing interesting physical phenomena occuring in small attractive systems. This motivates a rexamination of the exact solution for the attractive case in future studies.

All interested are invited to attend.
