Theoretical Cosmology meetings
To actively encourage the field of theoretical cosmology and to set an informal stage for the exchange of ideas, the Dutch theoretical cosmology community organizes Friday afternoon meetings approximately 6 times a year — usually on the first Friday of the month. The meetings typically start in the afternoon with a main speaker, followed by a short break to continue with another seminar or journal club discussion on some topic of current interest. We end the afternoon with drinks. The supporting institutes in Leiden, Amsterdam, Groningen, Utrecht where recently joined by the strings and cosmology group in Leuven and take turns in hosting the event.

Title: Stochastic Inflation and Primordial Black Holes
I will explain which signatures are left by this quantum backreaction on the correlation functions of primordial cosmological perturbations. I will discuss the conditions under which these can be large even at sub-Planckian energy, and I will explain which prospects it opens for probing quantum gravity effects on inflationary dynamics. As an application, I will show how the formation of primordial black holes from inflation is dominated by these stochastic effects.
