Long Cycles in the Infinite-Range-Hopping Bose-Hubbard Model with Hard Cores
G. Boland, J. V. Pulé
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 par…
Long Cycles in a Perturbed Mean Field Model of a Boson Gas
Teunis C. Dorlas, Philippe A. Martin, Joseph V. Pulé
In this paper we give a precise mathematical formulation of the relation between Bose condensation and long cycles and prove its validity for the perturbed mean field model of a Bo…
A Dicke Type Model for Equilibrium BEC Superradiance
Joseph V. Pule, Andre F. Verbeure, Valentin A. Zagrebnov
We study the effect of electromagnetic radiation on the condensate of a Bose gas. In an earlier paper we considered the problem for two simple models showing the cooperative effect…
Models for Equilibrium BEC Superradiance
Joseph V. Pule, Andre Verbeure, Valentin A. Zagrebnov
Motivated by recent experiments with superradiant Bose-Einstein Condensate (BEC) we consider simple microscopic models describing rigorously the interference of the two cooperative…
The Approximating Hamiltonian Method for the Imperfect Boson Gas
Joseph V. Pule, Valentin A. Zagrebnov
The pressure for the Imperfect (Mean Field) Boson gas can be derived in several ways. The aim of the present note is to provide a new method based on the Approximating Hamiltonian…
Thermodynamic Limit for Finite Dimensional Classical and Quantum Disordered Systems
P. Contucci, C. Giardina', J. Pule'
We provide a very simple proof for the existence of the thermodynamic limit for the quenched specific pressure for classical and quantum disordered systems on a -dimensional lat…
