L.Pinol:Observational signatures of multifield inflation

The aspects of modern cosmology related with new physics, predicted by particle theory are discussed here. The models of inflation, baryosynthesis, dark matter and dark energy, physics of very early Universe, cosmological nucleosynthesis, origin and properties of cosmic microwave background radiation, formation of large scale structure of the Universe, role and distribution of dark matter in the modern Universe are discussed here.

L.Pinol:Observational signatures of multifield inflation

New postby Maxim Khlopov on Tue 5 May 2020 14:33

VIA APC Theory seminar by Lucas Pinol "Observational signatures of multifield inflation" took place on 05.05.2020
Its presentation is attached and the record of the corresponding videoconference
will appear soon
The following questions were put in the course of talk

Deruelle: ll 2-d metrics are conformally flat (if I am correct). If this would simplify the pb wouldn’t it ?

Houri Ziaeepour: How do you define your initial condition ? for in-in calculation?

francesco: you replace F in the action? Not in the field equations? At the non-linear level this is generically not consistent, is it?

You are welcome to continue discussion of this topic in replies to this post
