Dynamics of nucleation in thermal phase transitions
Oliver Gould, Joonas Hirvonen, Andrey Shkerin +1
We study dynamical effects during nucleation in thermal first-order phase transitions in field theory. Focusing on the classical regime of the decay of a metastable state, we prese…

Simple third order operator-splitting schemes for stochastic mechanics and field theory
Andrey Shkerin, Sergey Sibiryakov
We present a method for constructing numerical schemes with up to 3rd strong convergence order for solution of a class of stochastic differential equations, including equations of…

Thermal False Vacuum Decay Is More Than It Seems
Dalila Pîrvu, Andrey Shkerin, Sergey Sibiryakov
We study the decay of a thermally excited metastable vacuum in classical field theory using real-time numerical simulations. We find a significantly lower decay rate than predicted…
