# From cold Fermi fluids to the hot QGP

## TL;DR

This paper reviews recent theoretical advances in understanding the nearly inviscid fluid behavior of strongly coupled quantum fluids, including ultracold Fermi gases and hot Quark-Gluon Plasma, despite their vastly different temperatures.

## Contribution

It provides a comparative summary of theoretical developments explaining fluid dynamical properties across different strongly coupled quantum fluids.

## Key findings

- Ultracold Fermi gases exhibit near-perfect fluidity.
- Similar fluid behavior observed in hot Quark-Gluon Plasma.
- Theoretical models connect these systems despite temperature differences.

## Abstract

Strongly coupled quantum fluids are found in different forms, including ultracold Fermi gases or tiny droplets of extremely hot Quark-Gluon Plasma. Although the systems differ in temperature by many orders of magnitude, they exhibit a similar almost inviscid fluid dynamical behavior. In this work, we summarize some of the recent theoretical developments toward better understanding this property in cold Fermi gases at and near unitarity.
