| « Inflationary correlators from the stochastic spectral expansion » |
|
Tommi Markkanen |
|
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. |
