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.

    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. 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.
