We show that for a range of strongly coupled theories with a first order phase transition, the domain wall or bubble velocity can be expressed in a simple way in terms of a perfect fluid hydrodynamic formula, and thus in terms of the equation of state. We test the predictions for the domain wall velocities using the gauge/gravity duality.

    hep-th 2026-07 conditional novelty 7.0 of 10

    Non-conformal equations of state introduce wall and flow obstructions that delete entire classes of bubble solutions and create 'shocked detonations', shrinking the allowed wall-velocity space and suppressing gravitat...

    hep-ph 2025-12 conditional novelty 6.0 of 10

    For pure SU(N) Yang-Mills dark sectors, confinement transitions produce gravitational waves too weak for LISA, ET, CE, DECIGO or BBO, with peak amplitude at N≈20 and a large-N decay h²Ω_peak ∝ N^{-14/3}.

  3. Phase transitions in an expanding medium -- hot remnants

    hep-th 2025-02 conditional novelty 6.0 of 10

    In an effective holographic model, expanding and cooling plasma forms 'hot remnants' that stay at the critical temperature while shrinking, then heat up during dissolution.

  4. Testing the effective action approach to bubble nucleation in holography

    hep-th 2025-07 conditional novelty 5.0 of 10

    A two-derivative holographic effective action reproduces critical bubble solutions from the full gravity theory to within a few percent across thin-wall and thick-wall regimes.
