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…
On the nature of Bose-Einstein condensation in disordered systems
Thomas Jaeck, Joseph V. Pulé, Valentin Zagrebnov
We study the perfect Bose gas in random external potentials and show that there is generalized Bose-Einstein condensation in the random eigenstates if and only if the same occurs i…
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…
