Mean-field Green’s-function theory of the two-sublattice Ising model in a transverse field

Edward B. Brown

Double-time Green's functions are used within a mean-field treatment of the two-sublattice Ising model in a transverse field. In contrast to previous treatments, a correct version of the spectral theorem is used to obtain a correct mean-field treatment for all spin. In particular, the dielectric constant is obtained for S=1. The results are markedly different from those of earlier treatments and are readily extended to four-sublattice models.

Ising Model with a Transverse Field

Roger James Elliott, Pierre M. Pfeuty, C Wood

The phase transition in the Ising model has been studied as a function of an applied transverse field, by Green's function and series-expansion methods. The critical indices are probably independent of the applied field except at $T=0$ where they appear to be related to those of the Ising model in one higher dimension.
