Phase transition within deformed Ising model
Abstract
Deformation of Ising Hamiltonian by means of replacing a site spin si by siq and statistics generalization with help of the substituting deformed probability piq instead of pi are studied jointly within mean--field scheme. Such deformed model is shown to be related to the phase transition of the second order with unusual set of critical indices depending essentially on the deformation parameter q. Scaling relations turn out to be invariant with respect to the deformation.
