New class of Gibbs measures for two state Hard-Core model on a Cayley tree (2306.03429v1)

Published 6 Jun 2023 in math.PR and math.FA

Abstract: In this paper, we consider a Hard-Core $(HC)$ model with two spin values on Cayley trees. The conception of alternative Gibbs measure is introduced and translational invariance conditions for alternative Gibbs measures are found. Also, we show that the existence of alternative Gibbs measures which are not translation-invariant. In addition, we study free energy of the model.
