dc.description.abstract | Classical-statistical lattice simulations provide a useful approximation to outof-equilibrium quantum field theory, but only for systems exhibiting large occupation numbers, and only for phenomena that are not intrinsically quantum mechanical in nature. In
certain special circumstances, it can be appropriate to initialize such real-time simulations
with quantum-like zero-point fluctuations. We will revisit these points, and investigate reports that quantum bubble nucleation rates in 1+1 dimensions can be computed through
the classical evolution of such a quantum-like initial condition [1]. We find that although
intriguing, the reported numerical agreement between classical-statistical simulations and
the quantum nucleation rate in 1+1 dimensions is a coincidence, which is not specific to
this choice of initialisation, is parameter and lattice cut-off dependent and disappears as
the number of space-dimensions increases from 1+1 to 2+1 | en_US |
