Fractional dimensional Fock space and Haldane's exclusion statistics. q/p case

preprint1995arXivOpen access

Abstract

The discussion of Fractional dimensional Hilbert spaces in the context of Haldane exclusion statistics is extended from the case \cite{IG} of g=1/pg=1/p for the statistical parameter to the case of rational g=q/pg=q/p with q,pq,p-coprime positive integers. The corresponding statistical mechanics for a gas of such particles is constructed. This procedure is used to define the statistical mechanics for particles with irrational gg. Applications to strongly correlated systems such as the Hubbard and t−Jt-J models are discussed.
