The Effects of Multiplicative Noise in Relativistic Phase Transitions
arXiv:hep-ph/0501168 · doi:10.1103/PhysRevD.71.105006
Abstract
Effective stochastic equations for the continuous transitions of relativistic quantum fields inevitably contain multiplicative noise. We examine the effect of such noise in a numerical simulation of a temperature quench in a 1+1 dimensional scalar theory. We look at out-of-equilibrium defect formation and compare our results with those of stochastic equations with purely additive noise.
