Flowing holographic anyonic superfluid

TL;DR

This paper studies the behavior of a strongly coupled anyonic superfluid using holographic models, identifying critical velocities for dissipation and instability as temperature varies.

Contribution

It introduces a holographic D3-D7' model to analyze the flow dynamics and stability of an anyonic superfluid, revealing critical velocities and instability conditions.

Findings

Critical superfluid velocity depends on temperature.

Flow becomes unstable at higher velocities without barriers.

Flow ceases to be dissipationless beyond a certain velocity.

Abstract

We investigate the flow of a strongly coupled anyonic superfluid based on the holographic D3-D7' probe brane model. By analyzing the spectrum of fluctuations, we find the critical superfluid velocity, as a function of the temperature, at which the flow stops being dissipationless when flowing past a barrier. We find that at a larger velocity the flow becomes unstable even in the absence of a barrier.
