TL;DR
This paper develops a holographic model to study aging phenomena, characterized by non-equilibrium criticality with Galilean and scaling symmetries but lacking time invariance, and confirms its predictions through correlation function calculations.
Contribution
It introduces a holographic framework for aging phenomena by deforming non-relativistic gauge/gravity duality, capturing non-equilibrium dynamics holographically.
Findings
Correlation functions match field theory expectations
Aging phenomena are modeled by complexifying bulk geometry
Holographic techniques successfully reproduce non-equilibrium criticality
Abstract
Aging phenomena are examples of `non-equilibrium criticality' and can be exemplified by systems with Galilean and scaling symmetries but no time translation invariance. We realize aging holographically using a deformation of a non-relativistic version of gauge/gravity duality. Correlation functions of scalar operators are computed using holographic real-time techniques, and agree with field theory expectations. At least in this setup, general aging phenomena are reproduced holographically by complexifying the bulk space-time geometry, even in Lorentzian signature.
