Title: (Ultra) Slow Roll with a Black Hole
Date (JST): Thu, Apr 02, 2026, 13:30 - 15:00
Place: Seminar Room A
Abstract:
What happens during inflation if there is a black hole? I will derive the slow roll conditions in the presence of a black hole and the back-reaction of the scalar on the black hole as well as commenting on time-dependent extended thermodynamics. I will then discuss what happens during a transition to ultra slow roll and how the black hole can "ring" the inflaton.
