The stochastic gravitational-wave backgrounds (SGWBs) from the cosmological first-order phase transitions (FOPTs) serve as a promising probe for the new physics beyond the standard model of particle physics. When most of the bubble walls collide with each other long after they had reached the terminal wall velocity, the dominated contribution to the SGWBs comes from the sound waves characterized by the efficiency factor of inserting the released vacuum energy into the bulk fluid motions… 

Searching for double-peak and doubly-broken gravitational-wave spectra from Advanced LIGO-Virgo's first three observing runs

The current LIGO-Virgo observing run has been pushing the sensitivity limit to touch the stochastic gravitational-wave backgrounds (SGWBs). However, no significant detection has been reported to date

Gravitational Waves and Primordial Black Hole Productions from Gluodynamics

We construct a holographic model describing the gluon sector of Yang-Mills theories at finite temperature in the non-perturbative regime. The equation of state as a function of temperature is in good



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 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

Hydrodynamic backreaction force of cosmological bubble expansion

As a promising probe for the new physics beyond the standard model of particle physics in the early Universe, the predictions for the stochastic gravitational wave background from a cosmological

Bubble wall dynamics at the electroweak phase transition

Abstract 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

Gravitational radiation from first-order phase transitions.

This work considers the stochastic background of gravity waves produced by first-order cosmological phase transitions from two types of sources: colliding bubbles and hydrodynamic turbulence and finds that the characteristic amplitude of the gravity wavesproduced is comparable to that from bubble collisions.

Energy budget and the gravitational wave spectra beyond the bag model

The energy budget of cosmological first-order phase transition is essential for the production of gravitational wave. Most of previous studies of energy budget are based on the bag model with same

Model-independent energy budget for LISA

We provide an easy method to obtain the kinetic energy fraction in gravitational waves, generated during a cosmological first-order phase transition, as a function of only the wall velocity and

Cosmological bubble friction in local equilibrium

In first-order cosmological phase transitions, the asymptotic velocity of expanding bubbles is of crucial relevance for predicting observables like the spectrum of stochastic gravitational waves, or

Sound velocity effects on the phase transition gravitational wave spectrum in the sound shell model

A cosmological first-order phase transition gravitational wave could provide a novel approach to studying the early Universe. In most cases, the acoustic gravitational wave from the sound wave

Towards an all-orders calculation of the electroweak bubble wall velocity

We analyze Higgs condensate bubble expansion during a first-order electroweak phase transition in the early Universe. The interaction of particles with the bubble wall can be accompanied by the
