Solitons as Probes of the Structure of Holographic Superfluids

TL;DR

This paper investigates how solitons can be used to probe the structure of holographic superfluids, revealing insights into their behavior and drawing parallels with BEC-BCS phenomena.

Contribution

It introduces a novel approach of using solitons to analyze holographic superfluids and compares their features across different scaling dimensions, highlighting BEC-BCS analogies.

Findings

Soliton length scales vary with the scaling dimension.

Superfluid critical velocity exhibits characteristic behavior.

Evidence supports the BEC-BCS analogy in holographic superfluids.

Abstract

Detailed features of solitons in holographic superfluids are discussed. Using solitons as probes, we study the behavior of holographic superfluids by varying the scaling dimension of the condensing operator, and build a comparison to the BEC-BCS comparison phenomena. Further evidence for this analogy is provided by the behavior of solitons' length scales as well as by the superfluid critical velocity.
