Fluxification and scalarization of the conifold black holes

TL;DR

This paper investigates phase transitions in a strongly coupled superconformal gauge theory, revealing fluxification and scalarization instabilities in the holographic dual black holes at critical chemical potentials.

Contribution

It introduces the phenomena of fluxification and scalarization in conifold black holes, showing how distinct instabilities lead to different phases in holographic models.

Findings

Two types of instabilities occur at the same critical chemical potential.

Different phases dominate in grand canonical versus microcanonical ensembles.

Condensates form for two distinct operators at the same critical point.

Abstract

We study thermal states of the strongly coupled Klebanov-Witten ${\cal N}=1$ superconformal gauge theory with R-symmetry chemical potential. The theory has two distinct dimension $\Delta=3$ chiral primary operators that develop a condensate at the same critical value of the chemical potential. One instability is associated with the spontaneous fluxification (the appearance of the 3-form flux) of the holographic dual black hole, while the other one is associated with the spontaneous scalarization (the activation of the deformation mode of the conifold). Different phases dominate in grand canonical and microcanonical ensembles.
