Abstract

|
|
| By making use of the early work of Kowalski (1972) [4] in this Journal, we expose the simplicity by which, for the Ising chain, the partition function Z(1) (beta J, beta h), where h denotes the applied magnetic field strength, can be constructed from the zero-field limit Z(1) (beta J, 0) plus the explicit factor cosh(beta h). Secondly, we use mean-field theory for the Ising model in four dimensions to prove a similar functional relation; namely that the partition function Z(4)(beta J, beta h) is again solely a functional of the zero field partition function Z(4)(beta J, 0) and beta h.
