We study the hydrodynamics of bubble expansion in cosmological first-order phase transition in the Friedmann-Lemaˆıtre- Robertson-Walker (FLRW) background with probe limit. Different from previous studies for fast first-order phase transition in flat background, we find that, for slow first-order phase transition in FLRW background with a given peculiar velocity of the bubble wall, the efficiency factor of energy transfer into bulk motion of thermal fluid is significantly reduced, thus…

Friction pressure on relativistic bubble walls
Abstract During a cosmological first-order phase transition, particles of the plasma crossing the bubble walls can radiate a gauge boson. The resulting pressure cannot be computed perturbatively for…

Energy budget of cosmological first-order phase transitions
The study of the hydrodynamics of bubble growth in first-order phase transitions is very relevant for electroweak baryogenesis, as the baryon asymmetry depends sensitively on the bubble wall…
Real-Time History of the Cosmological Electroweak Phase Transition.
TLDR
The macroscopic real-time history of the cosmological electroweak phase transition is studied, finding that collisions with compression waves may make the bubble walls oscillate, and that reheating to T-c generically takes place.
Gravitational waves from the sound of a first order phase transition.
TLDR
It is found that the compression waves in the fluid continue to be a source of GWs long after the bubbles have merged, a new effect not taken properly into account in previous modeling of the GW source.

Velocity of electroweak bubble walls
Lower bound on the electroweak wall velocity from hydrodynamic instability
The subsonic expansion of bubbles in a strongly first-order electroweak phase transition is a convenient scenario for electroweak baryogenesis. For most extensions of the Standard Model, stationary…

Stability of cosmological deflagration fronts
In a cosmological first-order phase transition, bubbles of the stable phase nucleate and expand in the supercooled metastable phase. In many cases, the growth of bubbles reaches a stationary state,…

It is believed that first-order phase transitions at or around the GUT scale will produce high-frequency gravitational radiation. This radiation is a consequence of the collisions and coalescence of…
