Multi-criticality of the three-dimensional Ising model with plaquette interactions: An extension of Novotny's transfer-matrix formalism

TL;DR

This study investigates the multi-critical behavior of the 3D gonihedric Ising model using an extended transfer-matrix approach, revealing its alignment with the 3D Ising universality class through finite-size scaling analysis.

Contribution

The paper extends Novotny's transfer-matrix method to analyze the 3D gonihedric Ising model for larger system sizes, clarifying its critical behavior and universality class.

Findings

The model exhibits multi-critical scaling consistent with the 3D Ising universality class.

Estimated crossover exponent 6=0.6(2) and correlation-length exponent 8=0.45(15).

Finite-size scaling analysis supports the model's alignment with standard critical behavior.

Abstract

Three-dimensional Ising model with the plaquette-type (next-nearest-neighbor and four-spin) interactions is investigated numerically. This extended Ising model, the so-called gonihedric model, was introduced by Savvidy and Wegner as a discretized version of the interacting (closed) surfaces without surface tension. The gonihedric model is notorious for its slow relaxation to the thermal equilibrium (glassy behavior), which deteriorate the efficiency of the Monte Carlo sampling. We employ the transfer-matrix (TM) method, implementing Novotny's idea, which enables us to treat arbitrary number of spins $N$ for one TM slice even in three dimensions. This arbitrariness admits systematic finite-size-scaling analyses. Accepting the extended parameter space by Cirillo and co-worker, we analyzed the (multi) criticality of the gonihedric model for N \le 13. Thereby, we found that, as first noted by Cirillo and co-worker analytically (cluster-variation method), the data are well described by the multi-critical (crossover) scaling theory. That is, the previously reported nonstandard criticality for the gonihedric model is reconciled with a crossover exponent and the ordinary three-dimensional-Ising universality class. We estimate the crossover exponent and the correlation-length critical exponent at the multi-critical point as \phi=0.6(2) and \nu=0.45(15), respectively.
