About

In this work, the dynamics of the nucleating scalar field is investigated during the first-order phase transitions by incorporating one-loop corrections of classical fluctuations. We contrast our results with traditional methods based on the derivative expansion; show that the latent heat can differ from the effective-potential result; and discuss general hydrodynamic corrections. Finally, an application of the presented framework for a simple scalar field model is shown, finding that the one-loop improvement decreases the wall speed and that an effective-potential approximation underestimates full one-loop corrections..
