Conformal to confining SQFTs from holography

TL;DR

This paper constructs new holographic duals for deformations of 4d SCFTs, analyzing their properties through Wilson loops, entanglement entropy, and a new measure of degrees of freedom, revealing insights into their IR and UV behaviors.

Contribution

It introduces three new families of smooth Type II string backgrounds dual to deformed 4d SCFTs, including novel global current VEVs and twisted compactifications.

Findings

Holographic Wilson loops and entanglement entropy are computed for the new backgrounds.

A monotonic quantity for degrees of freedom is proposed, interpolating between IR and UV regimes.

The backgrounds exhibit a flow from 4d SCFTs to 3d gapped theories.

Abstract

In this paper we present three new families of smooth Type II string theory backgrounds. These are dual to supersymmetry-preserving deformations of 4d SCFTs. The deformations include a VEV for a global current and a `twisted compactification' on a circle. We study various holographic aspects of the dual QFTs, focusing on Wilson loops and Entanglement Entropy. Additionally, we present a monotonic quantity calculating the density of degrees of freedom in terms of the energy, which interpolates between the IR 3d gapped theory and the 4d SCFT result. Other probes related to global aspects of the QFTs are briefly discussed.
