About
Phase transitions, in general, involve a nonzero spinodal temperature at which the potential barrier disappears. In some models of cosmological first-order phase transitions, supercooling is maintained until around the spinodal temperature, so the phase transition proceeds during the time when the potential barrier disappears rapidly. In this talk, I will discuss whether, in this circumstance, the phase transition is completed via bubbles or phase mixing driven by the growth of tachyonic modes. Based on our numerical simulations solving the Langevin equation, we conclude that the bubble nucleation picture is still valid even if the width and height of the potential barrier are smaller than the temperature scale. Therefore, the standard analysis based on bubble nucleation rate is applicable, assuming the bubble nucleation rate is properly calculated..
