Quantum stochastic processes in two dimensional space-time
arXiv:1505.04326
Abstract
Several stochastic processes with virtual particles in two dimensional space-time are presented whose mean field equations coincide with Schrödinger, Dirac, Klein-Gordon and the quantum mechanic equation for a photon. These processes could be used to detect discrete space-time features at the Planck scale.
