Description
I will discuss dynamical effects during critical bubble nucleation in thermal first-order phase transitions. These effects arise due to lack of local thermal equilibrium and affect the parameters of the transition including the nucleation rate. I will present a general method of calculating the thermal nucleation rate that accounts both for statistical and dynamical effects. I will also present results from real-time classical lattice simulations showing non-equilibrium features (such as oscillons) during the nucleation process. These results can be important in many areas, from cosmological phase transitions to studies of false vacuum decay in quantum simulators.
