Infinite Cycles in Boson Lattice Models
G. Boland
We study the relationship between long cycles and Bose-Einstein condensation (BEC) in the case of several models. A convenient expression for the density of particles on cycles of…

Long Cycles in the Infinite-Range-Hopping Bose-Hubbard Model
G. Boland
In this paper we study the relation between long cycles and Bose-Einstein condensation in the Infinite-Range Bose-Hubbard Model. We obtain an expression for the cycle density invol…
