Model spaces as constrained Hamiltonian systems: I. Application to
Glenn Barnich, Thomas Smoes
Motivated by group-theoretical questions that arise in the context of asymptotic symmetries in gravity, we study model spaces and their quantization from the viewpoint of constrain…

Boundary Conditions for Extremal Black Holes from 2d Gravity
Stéphane Detournay, Thomas Smoes, Raphaela Wutte
We devise new boundary conditions for the near-horizon geometries of extremal BTZ and Kerr black holes, as well as for the ultra-cold limit of the Kerr-de Sitter black hole. These…
