Abstract
Environment interaction may induce stochastic semiclassical dynamics in open quantum systems. In the gravitational context, stress-energy fluctuations of quantum matter fields give rise to a stochastic behaviour in the spacetime geometry. Einstein-Langevin equation is a suitable tool to take these effects into account when addressing the back-reaction problem in semiclassical gravity. We analyze within this framework the generation of gravitational fluctuations during inflation, which are of great interest for large-scale structure formation in cosmology.
