Coherent Bose-Einstein condensation with fluctuating density
L. Salasnich, A. Crisanti, A. Sarracino +1
Bose-Einstein condensation in the grand canonical ensemble admits a formulation in terms of a phase-density decomposition of the condensate mode operator . In the pr…
Bose-Einstein Condensation, Fluctuations and Spontaneous Symmetry Breaking
A. Crisanti, A. Sarracino, M. Zannetti
The realisation of Bose-Einstein condensation under grand-canonical conditions has provided the experimental evidence for the simultaneous occurrence of macroscopic fluctuations an…
Canonical vs. Grand Canonical Ensemble for Bosonic Gases under Harmonic Confinement
Andrea Crisanti, Luca Salasnich, Alessandro Sarracino +1
We analyze the general relation between canonical and grand canonical ensembles in the thermodynamic limit. We begin our discussion by deriving, with an alternative approach, some…
Condensation vs Ordering: From the Spherical Models to BEC in the Canonical and Grand Canonical Ensemble
A. Crisanti, A. Sarracino, M. Zannetti
In this paper we take a fresh look at the long standing issue of the nature of macroscopic density fluctuations in the grand canonical treatment of the Bose-Einstein condensation (…
