A generalization of Haldaneʹs state-counting procedure and π-deformations of statistics Original Research Article

We consider the generalization of Haldaneʹs state-counting procedure to describe all possible types of exclusion statistics which are linear in the deformation parameter g. The statistics are parametrized by elements of the symmetric group of the particles in question. For several specific cases we determine the form of the distribution functions which generalizes results obtained by Wu. Using them we analyze the low-temperature behavior and thermodynamic properties of these systems and compare our results with previous studies of the thermodynamics of a gas of g-ons. Various possible physical applications of these constructions are discussed.
