A microscopic model for Josephson currents
J. Lauwers, A. Verbeure
A microscopic model of a Josephson junction between two superconducting plates is proposed and analysed. For this model, the nonequilibrium steady state of the total system is expl…
Bose-Einstein Condensation for Homogeneous Interacting Systems with a One-Particle Spectral Gap
J. Lauwers, A. Verbeure, V. A. Zagrebnov
We prove rigorously the occurrence of zero-mode Bose-Einstein condensation for a class of continuous homogeneous systems of boson particles with superstable interactions. This is t…
Proof of Bose-Einstein Condensation for Interacting Gases with a One-Particle Spectral Gap
J. Lauwers, A. Verbeure, V. A. Zagrebnov
Using a specially tuned mean-field Bose gas as a reference system, we establish a positive lower bound on the condensate density for continuous Bose systems with superstable two-bo…
Fluctuations in the Bose Gas with Attractive Boundary Conditions
J. Lauwers, A. Verbeure
In this paper limiting distribution functions of field and density fluctuations are explicitly and rigorously computed for the different phases of the Bose gas. Several Gaussian an…
Metastability in the BCS model
Joris Lauwers, Andre Verbeure
We discuss metastable states in the mean-field version of the strong coupling BCS-model and study the evolution of a superconducting equilibrium state subjected to a dynamical semi…
BEC for a Coupled Two-type Hard Core Bosons Model
Joris Lauwers, Andre Verbeure
We study a solvable model of two types hard core Bose particles. A complete analysis is given of its equilibrium states including the proof of existence of Bose-Einstein condensati…
