On the existence of a finite-temperature transition in the two-dimensional gauge glass

TL;DR

This paper uses Monte Carlo simulations and finite-size scaling to investigate whether a two-dimensional gauge glass exhibits a finite-temperature transition, concluding it does not support spin-glass order at finite temperatures.

Contribution

It provides evidence against the existence of a finite-temperature transition in the 2D gauge glass, challenging earlier claims.

Findings

No finite-temperature spin-glass order detected

Finite-size scaling indicates zero-temperature transition

Results contrast with previous studies claiming finite-temperature transition

Abstract

Results from Monte Carlo simulations of the two-dimensional gauge glass supporting a zero-temperature transition are presented. A finite-size scaling analysis of the correlation length shows that the system does not exhibit spin-glass order at finite temperatures. These results are compared to earlier claims of a finite-temperature transition.
