Is local scale invariance a generic property of ageing phenomena ?

TL;DR

This paper investigates whether local scale invariance universally describes ageing phenomena, specifically analyzing the 1+1-dimensional contact process, and finds it does not align with the theory's predictions.

Contribution

The study challenges the applicability of local scale invariance to the critical autoresponse function of the contact process.

Findings

Critical autoresponse function does not agree with local scale invariance predictions.

Contradicts recent claims supporting local scale invariance as a universal property.

Highlights limitations of local scale invariance in describing certain ageing phenomena.

Abstract

In contrast to recent claims by Enss, Henkel, Picone, and Schollwoeck [J. Phys. A 37, 10479] it is shown that the critical autoresponse function of the 1+1-dimensional contact process is not in agreement with the predictions of local scale invariance.
