Abstract

For the υ-dimensional lattice boson gas with the onsite repulsion and nearest neighbour sites attraction, we prove the existence of phase transition for ν≥3 and sufficiently large density when temperature is sufficiently small. This phase transition is connected with some type of Bose-Einstein condensation (ρ-condensation.4).
