Abstract:
The critical values of coupling for the Bassichis–Foldy model are explained. For a finite number of bosons N they are associated with changes in the bounded above and below properties of the Hamiltonian. Exact N → ∞ spectral properties are obtained using continued fractions and a duality in terms of competing Bogoliubov-type limits is exhibited. The critical coupling limits are then associated with transitions from either a discrete to a continuous spectrum or from one Bogoliubov-type limit to another.
