Superfluidity in Super-Yang-Mills Theory

TL;DR

This paper explores the potential superfluid behavior in strongly interacting gauge theories using AdS/CFT correspondence, analyzing vortex formation and quantization near a zero-viscosity point in the phase diagram.

Contribution

It introduces a framework for describing superfluidity in gauge theories via AdS/CFT, including vortex construction and quantization analogues.

Findings

Vortices can be constructed in the superfluid phase.

Quantization of vorticity has an AdS analogue.

Vortex production may occur in quark-gluon plasma during collisions.

Abstract

The AdS/CFT correspondence suggests that there is a point in the phase diagram of strongly interacting gauge-theory matter where the viscosity approaches zero. This paper analyses the possibility that this point represents a superfluid and that the the system near this point in the phase diagram can be described by a Landau fluid. Superfluid vortices are constructed and the AdS analogue of vorticity quantisation is described. The production of vortices in the quark-gluon plasma during heavy ion collisions is discussed.
