Bose-Einstein condensation without chemical potential
Large-volume, high-temperature Bose-Einstein condensation is illustrated for a relativistic O(2)-invariant scalar field with fixed charge using the canonical ensemble. The standard, grand canonical results are reproduced for the infinite-volume limit. Finite-volume corrections are calculated and the results are found to differ from the grand canonical approximation in a consistent qualitative w...
متن کاملNumerical analysis of Bose–Einstein condensation in a three-dimensional harmonic oscillator potential
Bose–Einstein condensation is the anomalous accumulation of particles in the ground state of a system of bosons, when compared with the population in a system of particles obeying classical statistics. I use undergraduate-level statistical mechanics and a symbolic algebra computer program to study the occupation numbers of the energy levels of a finite number of noninteracting particles confine...
متن کاملBose-Einstein condensation of atomic gases in a general harmonic-oscillator confining potential trap.
Abstract: We present an analysis of Bose-Einstein condensation for a system of noninteracting spin-0 particles in a harmonic oscillator confining potential trap. We discuss why a confined system of particles differs both qualitatively and quantitatively from an identical system which is not confined. One crucial difference is that a confined system is not characterized by a critical temperature...
متن کاملBose-Einstein condensation of atoms in a uniform potential.
We have observed the Bose-Einstein condensation of an atomic gas in the (quasi)uniform three-dimensional potential of an optical box trap. Condensation is seen in the bimodal momentum distribution and the anisotropic time-of-flight expansion of the condensate. The critical temperature agrees with the theoretical prediction for a uniform Bose gas. The momentum distribution of a noncondensed quan...
متن کاملharmonic analysis on amenable networks and the Bose-Einstein Condensation
We present the new and unexpected results concerning the Bose–Einstein Condensation for the Pure Hopping Model, describing the thermodynamic behaviour of Bardeen–Cooper pairs in arrays of Josephson junctions located on non homogeneous amenable networks. For this particular situation arising from physics, the results are obtained by a detailed analysis concerning harmonic analysis of the adjacen...
