9. Non-perturbative quantisation of impulsive radiative data

Wolfgang Wieland (FAU Erlangen-Nürnbreg)

6/25/24, 5:10 PM

Talk

This talk gives a broad introduction into an emerging field at the interface of quantum foundations and quantum gravity. What connects these different research areas are common questions of shared interest: What is the causal structure at the quantum level? What is the role of the equivalence principle at the quantum level? Are the reference frames classical or quantum? After a brief...

36. Canonical structure, Dressing time and and quantization of null geometry.

Laurent Freidel (Zoom) (Perimeter Institute )

6/25/24, 5:50 PM

In this talk, I will review our recent work with L. Ciambelli and R. Leigh, focusing on the non-perturbative characterization of the gravitational phase space along null boundaries.

I will present the construction of the Carrollian curved geometry, the Poisson bracket and discuss the construction of a field-dependent time called dressing time that allows the construction of a positive...

14. Spherical collapse and black hole evaporation

Madhavan Varadarajan (Zoom) (RRI)

6/25/24, 6:30 PM

We consider spherically symmetric gravity coupled to a spherically symmetric scalar field with a specific coupling which depends on the Areal Radius. Suitable boundary conditions ensure the existence of an axis of symmetry and consequently a single asymptotic past and future (as opposed to a pair of left and right ones). The scalar field stress energy takes the form of null dust. Its classical...
