Abstract

I describe a recently derived stochastic approach to inflaton dynamics which provides a framework for understanding the dynamics of a quantum scalar field driving an inflationary phase. This theory can address some serious problems associated with the conventional textbook approach. Specifically, it can address the quantum-to-classical transition problem, and it will be shown to lead to a dramatic easing of the fine tuning constraints that have plagued inflation theories.
