Vacuum bubbles from cosmic ripples
Zi-Yan Yuwen, Rong-Gen Cai, Shao-Jiang Wang
We investigate vacuum decays in the early Universe in the presence of curvature perturbations. For sufficiently large perturbations associated with over-densities, we find that the…
Bubble wall velocity from number density current in (non)equilibrium
Zi-Yan Yuwen, Jun-Chen Wang, Shao-Jiang Wang
Cosmological first-order phase transitions (FOPTs) serve as comprehensive probes into our early Universe with associated generations of stochastic gravitational waves and superhori…
General bubble expansion at strong coupling
Jun-Chen Wang, Zi-Yan Yuwen, Yu-Shi Hao +1
The strongly coupled system like the quark-hadron transition (if it is of first order) is becoming an active play yard for the physics of cosmological first-order phase transitions…
General backreaction force of cosmological bubble expansion
Jun-Chen Wang, Zi-Yan Yuwen, Yu-Shi Hao +1
The gravitational-wave energy-density spectra from cosmological first-order phase transitions crucially depend on the terminal wall velocity of asymptotic bubble expansion when the…
The energy budget of cosmological first-order phase transitions beyond the bag equation of state
Shao-Jiang Wang, Zi-Yan Yuwen
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…
Hydrodynamic backreaction force of cosmological bubble expansion
Shao-Jiang Wang, Zi-Yan Yuwen
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…
