Ising Models with Holes: Crossover Behavior

Helen Au-Yang,
Jacques H. H. Perk

Abstract: In order to investigate the effects of connectivity and proximity in the specific heat, a special class of exactly solvable planar layered Ising models has been studied in the thermodynamic limit. The Ising models consist of repeated uniform horizontal strips of width m connected by sequences of vertical strings of length n mutually separated by distance N , with N = 1, 2 and 3. We find that the critical temperature T c (N, m, n), arising from the collective effects, decreases as n and N increase, and increase… Show more

“…The specific heat is the second derivative of the free energy which is specifically given by (3.35) together with (3.29) on p. 92 in the book [5]. Thus the specific heats shown in paper I [1], are the results of differentiating the free energy given by (90).…”
