DESCRIPTION:Andrey Shkerin (Perimeter Institute)\nAbstract:\nWe study deca
 y of a thermally excited metastable vacuum in classical field theory using
  real-time numerical simulations. We find a significant reduction of the d
 ecay rate compared to the prediction of the standard thermal theory. The d
 iscrepancy is due to violation of thermal equilibrium during nucleation of
  the critical bubble and is reduced by introducing dissipation and noise i
 n the field equations of motion. We propose a condition to ensure thermal 
 equilibrium throughout the nucleation process and show that it is violated
  in Hamiltonian dynamics of a single field. For theories with multiple fie
 lds the condition may or may not be satisfied depending on the model detai
 ls. \n\n\n
