Zeros of the Partition Function and Pseudospinodals in Long-Range Ising Models

Condensed Matter 2009-11-10 v2

Abstract

The relation between the zeros of the partition function and spinodal critical points in Ising models with long-range interactions is investigated. We find the spinodal is associated with the zeros of the partition function in four-dimensional complex temperature/magnetic field space. The zeros approach the real temperature/magnetic field plane as the range of interaction increases.
