Long Cycles in the Infinite-Range-Hopping Bose-Hubbard Model with Hard Cores
arXiv:0806.0791 · doi:10.1007/s10955-008-9586-z
Abstract
In this paper we study the relation between long cycles and Bose-Condensation in the Infinite range Bose-Hubbard Model with a hard core interaction. We calculate the density of particles on long cycles in the thermodynamic limit and find that the existence of a non-zero long cycle density coincides with the occurrence of Bose-Einstein condensation but this density is not equal to that of the Bose condensate.
