Resumen:

In the experimental devices used for Bose-Einstein condensation the gas is trapped resorting to magneto-optical methods. In other words, the concept of volume of the corresponding container (as usually found in any text book on statistical mechanics) becomes in these experiments a rather vague parameter. In the present work we deduce the concepts of volume and pressure (as a function of the variables associated to the trap) that allow us to define the corresponding ensembles. Additionally, the issue of the fluctuations in the number of particles is addressed. © 2010 by World Scientific Publishing Co. Pte. Ltd. All Rights Reserved.
