Bose-Einstein condensation of quasiparticles is excluded in the van Hove model because time cluster properties on beta-KMS states preclude it and nonlinear dispersion with s greater than 2 reduces the observable algebra via infrared divergences.

The paper establishes the equivalence between direct integral decompositions of finite-temperature BEC states in the resolvent algebra and ergodic decompositions of associated probability measures in the functional integral approach for the free Bose gas.
Operator algebras and probability theory supply guiding principles for constructive quantum field theory and rigorous statistical mechanics.
The paper is a set of notes on the van Hove model that covers cutoff removal, existence of ground and KMS states for a point source, and Bose-Einstein condensation in infinite volume, but states it contains no essentially new results.
