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.

March 9 @ 08:00 - 17:00

Utrecht, March 9th, 2018

The meeting will take place at Utrecht University, Buys Ballot building (BBG)

14:00-15:00 Talk by Cristiano Germani (Barcelona University),

Title:Primordial Black Holes from single field inflation

Abstract:

In this talk I will discuss whether primordial black holes can be formed, and under which conditions, by large (small-scales) curvature perturbations generated during single field inflation.

15:00 – 15:30 Coffee

15:30-16:30 Talk by Diederik Roest (Groningen university)

Title:Can the vector be a Goldstone boson?

Abstract:

Non-linear symmetries for scalars play an important role in many fields of physics, including cosmology. We will provide a pedagogical review of the scalar case, and then turn towards the fermion and the vector: can one realize similar non-linear symmetries on these fields? In the vector case, we will investigate this question from a number of perspectives, including coset constructions and generalized geometry.

17:00 Borrel
