Claims

C1strongest claim

A zero-temperature, deconfinement, first-order phase transition appears at one end of this branch of solutions. It is triggered by the strength of the flux, setting an upper bound on the magnitude of the magnetic flux that can be supported by the geometry. Two scalar particles are the lightest in the spectrum, their masses being suppressed and almost degenerate across the whole parameter space.

C2weakest assumption

The background solutions of Romans supergravity with magnetic flux are valid, regular, and correctly identified as holographic duals to confining four-dimensional field theories; the fluctuation analysis around these backgrounds faithfully captures the bound-state spectrum without significant back-reaction or higher-derivative corrections.

C3one line summary

Holographic duals from Romans supergravity with Abelian magnetic flux yield confining 4D theories with a flux-driven zero-temperature deconfinement transition and a spectrum dominated by two nearly degenerate light scalars, one a dilaton.
