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, with bubble walls propagating as detonations or deflagrations. However, these hydrodynamical solutions may be unstable under corrugation of the interface. Such instability may drastically alter some of the cosmological consequences of the phase transition. Here, we study the hydrodynamical stability… 

Bubble wall dynamics at the electroweak phase transition

First order phase transitions could play a major role in the early universe, providing important phenomenological consequences, such as the production of gravitational waves and the generation of

Supercool subtleties of cosmological phase transitions

We investigate rarely explored details of supercooled cosmological first-order phase transitions at the electroweak scale, which may lead to strong gravitational wave signals or explain the cosmic

Model-independent energy budget of cosmological first-order phase transitions—A sound argument to go beyond the bag model

We study the energy budget of a first-order cosmological phase transition, which is an important factor in the prediction of the resulting gravitational wave spectrum. Formerly, this analysis was

Energy budget of cosmological first-order phase transition in FLRWbackground

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

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

From Boltzmann equations to steady wall velocities

By means of a relativistic microscopic approach we calculate the expansion velocity of bubbles generated during a first-order electroweak phase transition. In particular, we use the gradient

Bubble expansion and the viability of singlet-driven electroweak baryogenesis

A bstractThe standard picture of electroweak baryogenesis requires slowly expanding bubbles. This can be difficult to achieve if the vacuum expectation value (VEV) of a gauge singlet scalar field

Bubble expansion and the viability of singlet-driven electroweak baryogenesis

The standard picture of electroweak baryogenesis requires slowly expanding bubbles. This can be difficult to achieve if the vacuum expectation value (VEV) of a gauge singlet scalar field changes
