Consider a one-dimensional spin 1 model, defined by the Hamiltonian N N H=-JS;Si+1+DS?, where J > 0, D > 0 and Si = -1,0, 1 (a) Use of periodic conditions of contour , calculate the automatic values of the transfer matrix. (b) Calculate the internal energy and entropy per spin. (c) What is the ground state (T = 0) of this model as a function of the parameter d = DIJ Get an asymptotic form of the eigenvalues of the download matrix, t - 0 in the d-axis regions
