"Inflationary correlators from the stochastic spectral expansion"

Tommi Markkanen
National Institute of Chemical Physics And Biophysics (Tallinn, Estonie)

In this talk I will discuss the slightly lesser known stochastic
spectral expansion and show how it can be used to calculate correlation
functions generated during inflation for various potentials. I will also
discuss the shortcomings of some of the commonly used approximations.
Finally I present the full stochastic calculation for the isocurvature
spectrum of a decoupled spectator, which demonstrates that it is a
viable candidate of dark matter.
