We study spherically symmetric bubble growth and droplet decay in first order cosmological phase transitions, using a numerical code including both the complete hydrodynamics of the problem and a phenomenological model for the microscopic entropy producing mechanism at the phase transition surface. The small-scale effects of finite wall width and surface tension are thus consistently incorporated. We verify the existence of the different hydrodynamical growth modes proposed recently and investigate the problem of a decaying quark droplet in the QCD phase transition. We find that the decaying droplet leaves behind no rarefaction wave, so that any baryon number inhomogeneity generated previously should survive the decay.

  1. Steady-state bubbles beyond local thermal equilibrium

    astro-ph.CO 2024-11 conditional novelty 7.0 of 10

    A new matching condition that includes entropy production reveals that fast detonation bubble walls and slower deflagration walls can both be stable, with the fast solution typically winning in practice.

  2. Thermalization effects on the dynamics of growing vacuum bubbles

    hep-ph 2024-11 conditional novelty 6.0 of 10

    Bubble-wall terminal velocity depends on plasma thermalization; non-equilibrium and free-streaming regimes give slower or different walls, and stationary solutions can be bypassed by runaways.

  3. Detecting gravitational waves from cosmological phase transitions with LISA: an update

    astro-ph.CO 2019-10 unverdicted novelty 4.0 of 10

    Updated LISA detection prospects for gravitational waves from phase transitions are derived from state-of-the-art sound-wave simulations, with a new web tool PTPlot provided for parameter scans.
