Description
I will discuss dynamical effects during 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 dynamical nucleation rate. I will also present results from real-time classical lattice simulations, which show the importance of the non-perturbative contribution to the dynamical prefactor arising from large coherent field fluctuations. These results can be important in many areas, from cosmological phase transitions to studies of false vacuum decay in quantum simulators.
