Critical exponents in spin glasses : numerics and experiments

TL;DR

This paper reviews numerical and experimental estimates of critical exponents in spin glasses, highlighting strong evidence that these exponents do not follow a universal behavior across different systems.

Contribution

It provides a comprehensive overview of existing estimates and emphasizes the non-universality of critical exponents in spin glasses.

Findings

Strong evidence for breakdown of universality in spin glass exponents

Numerical and experimental estimates show significant variation

Highlights need for revised theoretical understanding

Abstract

We give an overview of numerical and experimental estimates of critical exponents in Spin Glasses. We find that the evidence for a breakdown of universality of exponents in these systems is very strong.
