STATISTICAL INTERACTIONS IN STATISTICAL-MODELS

We regard Haldane's generalized Pauli exclusion principle as the stati stical interactions and apply this concept tu the statistical models. With proper choice of particle species, it is possible to transform a model with intertwined interactions bt tween spins into another with s pecies of (free) particles with statistical interactions and all the t hermodynamic properties can Le obtained straightforwardly. We use two simple examples of one-dimensional spin chain to describe this approac h.
