We revisit a one-parameter family of three-dimensional gauge theories with known supergravity duals. We show that three infrared behaviors are possible. For generic values of the parameter, the theories exhibit a mass gap but no confinement, meaning no linear quark-antiquark potential; for one limiting value of the parameter the theory flows to an infrared fixed point; and for another limiting value it exhibits both a mass gap and confinement. Theories close to these limiting values exhibit quasi-conformal and quasi-confining dynamics, respectively. Eleven-dimensional supergravity provides a simple, geometric explanation of these features.

  1. Complexity measures in holographic cascading theories with multiscale dynamics

    hep-th 2026-08 accept novelty 6.0 of 10

    In holographic B8 gauge theories, complexity growth flattens near a walking conformal regime, while Krylov oscillation periods track the infrared scale and persist in screened, non-confining phases.

  2. Light dilaton from top-down holographic confinement with magnetic fluxes

    hep-th 2026-02 conditional novelty 6.0 of 10

    In a two-flux family of top-down holographic confining theories, the lightest scalar is an approximate dilaton with mass about one tenth of the lightest spin-2 confinement scale, over a wide, untuned region of paramet...

    hep-th 2024-11 conditional novelty 6.0 of 10

    In the holographic Klebanov-Witten plasma, D5-brane bubbles nucleate with a preferred flux that grows as 1/(T-Tc)^2, and their walls move at speeds below the conformal sound speed.

  4. Cosmic censorship in a (dual) collider

    hep-th 2024-11 conditional novelty 6.0 of 10

    In holographic models with a good-singularity ground state, a boost-invariant expanding fluid drives the dual horizon curvature to diverge in classical gravity.
