Primordial black holes spin from cosmological first-order phase transitions
Yu-Shi Hao
The stochastic bubble nucleation during cosmological first-order phase transitions leads to variations in the phase transition initiation times across different Hubble volumes, the…
Primordial black holes and curvature perturbations from false vacuum islands
Rong-Gen Cai, Yu-Shi Hao, Shao-Jiang Wang
Recently, much attention has been focused on the false vacuum islands that are flooded by an expanding ocean of true-vacuum bubbles slightly later than most of the other parts of t…
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…
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…
