Perfect Fluidity in Atomic Physics

TL;DR

This paper explores the potential for perfect fluidity, characterized by minimal shear viscosity, to occur in strongly coupled non-relativistic Fermi liquids with infinite scattering length, inspired by observations in quark-gluon plasma.

Contribution

It proposes that perfect fluidity, known in relativistic quark-gluon plasma, may also manifest in non-relativistic Fermi liquids with infinite scattering length.

Findings

Potential realization of perfect fluidity in non-relativistic Fermi liquids.

Extension of fluidity concepts from relativistic to non-relativistic systems.

Theoretical exploration of strongly coupled Fermi systems with large scattering length.

Abstract

Experimental results obtained at the Relativistic Heavy Ion Collider (RHIC) have been interpreted in terms of a strongly interacting quark gluon plasma. The strongly interacting plasma is characterized by ``perfect fluidity'', i.e. a ratio of shear viscosity to entropy density that saturates a proposed lower bound. In this contribution we explore the possibility that a similar phenomenon takes place in a strongly coupled non-relativistic Fermi liquid in which the scattering length between the Fermions is infinitely large.
