String theory scalar potentials and their critical points

March 13, 2023 @ 11:00 am - 12:00 pm

Swampland Seminar

Speaker: David Andriot (Annecy, LAPTH)

Title: String theory scalar potentials and their critical points

Abstract: Positive scalar potentials in string effective theories could provide an origin to Dark Energy, responsible for the accelerated expansion of our universe today or during inflation. It is thus crucial to characterize these scalar potentials, namely their slope, their critical points (de Sitter solutions) and the associated stability, as also advocated by the Swampland Program. We will present such characterizations. Going further, we will also discuss negative scalar potentials, and make related observations on anti-de Sitter solutions, in particular on a new mass bound, as well as comments on scale separation.
