Title: Fundamental physics with cold and ultracold neutrons

Abstract: Thanks to their lack of charge, neutrons can be powerful probes to study fundamental aspects of the weak and strong nuclear forces unhampered by electromagnetic effects. However, for the same reason tools and techniques to make neutrons useful for fundamental physics are quite different from other fields of subatomic physics. This presentation will explain the principles of neutron production, moderation and transport and showcase examples of the fundamental physics that can be explored with neutrons.

Title: Hamiltonian approach to near extremal black hole physics

Abstract: Much progress has been made in recent years on understanding near-extremal black holes, primarily through the Euclidean path integral. These findings include large backreaction effects at both classical and quantum levels.  However, a Lorentzian formulation of these effects, as needed to describe black holes formed from collapse along with other dynamical processes, is not well understood. I will describe an approach to this problem based on the Hamiltonian formulation of gravity. In this formulation we can make contact with earlier Euclidean results while also generalizing to inherently Lorentzian processes like black hole formation.
