TL;DR

This paper confirms that the non-equilibrium exponent a in the 2D Ising model is 1/2, contradicting previous claims of a value of 1/4, through analysis of susceptibility scaling.

Contribution

The study provides a definitive measurement of the exponent a in the 2D Ising model, clarifying discrepancies in prior research.

Findings

Confirms a=1/2 for the exponent a in 2D Ising model

Contradicts previous claim of a=1/4 by Corberi et al.

Uses dynamical scaling of susceptibility for measurement.

Abstract

The value of the non-equilibrium exponent $a$ is measured in the two-dimensional (2D) Ising model quenched to below criticality from the dynamical scaling of the zero-field-cooled and the intermediate susceptibility. Our results fully reconfirm the expected value $a=1/2$ but are inconsistent with the value $a=1/4$, advocated by Corberi, Lippiello and Zannetti (cond-mat/0506139).
