Condensation in the Backgammon model

We analyse the properties of a very simple ''balls-in-boxes'' model which can exhibit a phase transition between a fluid and a condensed phase, similar to the behaviour encountered in models of random geometries in one, two and four dimensions. This model can be viewed as a generalization of the backgammon model introduced by Ritort as an example of glassy behaviour without disorder. Published by Elsevier Science B.V.
