Title: Stochastic Effects Beyond Inflation

Place: Seminar Room A
Abstract: I explore the extension of the stochastic formalism to non inflationary early universe scenarios, focusing on bouncing cosmologies with exponential scalar-field potentials. The framework is formulated directly in phase space, enabling a unified description across classical contraction and the bounce. I outline the conceptual and technical challenges involved in applying stochastic methods beyond inflation and discuss the consistency requirements that must be addressed in this setting.
