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 Diederik Roest (Groningen university)

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
