Nonlinear growth and amplification of phase-transition gravitational waves induced by cosmic expansion
Xiao Wang, Chi Tian, Csaba Balázs
We perform the first three-dimensional hydrodynamical simulations of cosmological first-order phase transitions in an expanding background. These simulations consistently incorpora…
HydroGrav: Precise hydrodynamics and gravitational waves for cosmological phase transitions
Flynn Linton, William Searle, Xiao Wang +1
We present HydroGrav, a C++ code used to construct self-similar fluid profiles, using the exact equation of state determined directly from the effective potential, for any particle…
How large are curvature perturbations from slow first-order phase transitions? A gauge-invariant analysis
Xiao Wang, Csaba Balázs, Ran Ding +1
When strongly supercooled cosmological first-order phase transitions (FOPTs) are sufficiently slow, super-horizon inhomogeneities can be generated. We compute these super-horizon c…
