Klein-Gordon-Langevin Quantum Geometry
F. Vanderseypen
Abstract
We present a quantum geometric framework for stochastic quantisation in the case of a free Klein-Gordon field on Euclidean space. In this approach the noise is part of the background space, spacetime is fuzzy. We extend the notion of sharp point limit and show how fuzzy spacetime and the Klein-Gordon field gives the Euclidean space and the stochastically quantised Klein-Gordon field respectively.
