Abstract

In this talk I will discuss some recent results obtained in collaboration with Jon Links, R. McKenzie and H.-Q. Zhou on the level spacing distribution of some integrable models for Bose-Einstein Condensates. We will discuss two models: the two-site Bose-Hubbard Model which has been studied in connection to tunnelling of condensates and the hetero-atomic-molecular Bose-Einstein Condensate Model, which in some sense can be regarded as a generalisation of the former. In particular I will present strong numerical evidence that these models exhibit a Poissonian gap distribution for various ranges of coupling parameters.
 

All interested are invited to attend.
