Universality far from equilibrium: From superfluid Bose gases to heavy-ion collisions

TL;DR

This paper explores the universal behavior of far-from-equilibrium quantum systems, linking superfluid Bose gases and heavy-ion collisions through a dual scalar field theory approach.

Contribution

It introduces a theoretical framework connecting non-Abelian plasmas to Bose condensates, revealing new universality classes far from equilibrium.

Findings

Evidence of duality between non-Abelian plasmas and scalar field theories

Identification of universality classes in far-from-equilibrium quantum systems

Theoretical insights into over-population effects in extreme conditions

Abstract

Isolated quantum systems in extreme conditions can exhibit unusually large occupancies per mode. This over-population gives rise to new universality classes of many-body systems far from equilibrium. We present theoretical evidence that important aspects of non-Abelian plasmas in the ultra-relativistic limit admit a dual description in terms of a Bose condensed scalar field theory.
