Condensate Fragmentation in a New Exactly Solvable Model for Confined Bosons

Mesoscale and Nanoscale Physics 2009-10-31 v2 Nuclear Theory

Abstract

Based on Richardson's exact solution of the pairing model and the Gaudin model for spin systems we derive a new class of exactly solvable models for finite boson system. As an example we solve a particular hamiltonian which displays a transition to a fragmented condensate for repulsive pairing interactions.
