Creation of NOON states by double Fock-state/Bose-Einstein condensates
W. J. Mullin \and F. Laloë
NOON states (states of the form where and are single particle states) have been used for predicting violations of hidden-variable theories (…
Quantum properties of a single beam splitter
F. Laloë, W. J. Mullin
When a single beam-splitter receives two beams of bosons described by Fock states (Bose-Einstein condensates at very low temperatures), interesting generalizations of the two-photo…
Beyond spontaneously broken symmetry in Bose-Einstein condensates
W. J. Mullin, F. Laloë
Spontaneous symmetry breaking (SSB) for Bose-Einstein condensates cannot treat phase off-diagonal effects, and thus not explain Bell inequality violations. We describe another situ…
Classical phases and quantum angles in the description of interfering Bose-Einstein condensates
W. J. Mullin, F. Laloë
The interference of two Bose-Einstein condensates, initially in Fock states, can be described in terms of their relative phase, treated as a random unknown variable. This phase can…
The origin of phase in the interference of Bose-Einstein condensates
W. J. Mullin, R. Krotkov, F. Laloë
We consider the interference of two overlapping ideal Bose-Einstein condensates. The usual description of this phenomenon involves the introduction of a so-called condensate wave f…
Bose-Einstein Condensation, Fluctuations, and Recurrence Relations in Statistical Mechanics
W. J. Mullin, J. P. Fernández
We calculate certain features of Bose-Einstein condensation in the ideal gas by using recurrence relations for the partition function. The grand canonical ensemble gives inaccurate…
The Two-Dimensional Bose-Einstein Condensate
Juan Pablo Fernandez, William J. Mullin
We study the Hartree-Fock-Bogoliubov mean-field theory as applied to a two-dimensional finite trapped Bose gas at low temperatures and find that, in the Hartree-Fock approximation,…
Bose-Einstein Condensation in a Harmonic Potential
W. J. Mullin
We examine several features of Bose-Einstein condensation (BEC) in an external harmonic potential well. In the thermodynamic limit, there is a phase transition to a spatial Bose-Ei…
Ursell Operators in Statistical Physics III: thermodynamic properties of degenerate gases
P. Grüter, F. Laloë, A. E. Meyerovich +1
We study in more detail the properties of the generalized Beth Uhlenbeck formula obtained in a preceding article. This formula leads to a simple integral expression of the grand po…
