Spontaneous current in an holographic s+p superfluid

TL;DR

This paper investigates a holographic superfluid model using Maxwell-Proca theory in AdS black hole backgrounds, revealing rich phase diagrams and spontaneous current formation in s+p-wave superfluids.

Contribution

It introduces a holographic model with Maxwell-Proca fields that captures s, p, and s+p superfluid phases, including spontaneous current phenomena.

Findings

Rich phase diagrams depending on operator dimension

Existence of s, p, and s+p superfluid solutions

Spontaneous current emergence in s+p-wave superfluids

Abstract

We study a Maxwell-Proca action in an asymptotically AdS black hole background. When moving the temperature of the black hole, we find rich phase diagrams having, that depend strongly on the dimension of the operator dual to the Proca field . We present different solutions in the bulk that correspond to the holographic dual for $s$, $p$ or $s+p$-wave superfluids. In the last case we observe the onset of a spontaneously induced current.
