Geometric action for extended Bondi-Metzner-Sachs group in four dimensions
Glenn Barnich, Kevin Nguyen, Romain Ruzziconi
The constrained Hamiltonian analysis of geometric actions is worked out before applying the construction to the extended Bondi-Metzner-Sachs group in four dimensions. For any Hamil…

Phase transition of photons and gravitons in a Casimir box
Ankit Aggarwal, Glenn Barnich
A first order phase transition for photons and gravitons in a Casimir box is studied analytically from first principles with a detailed understanding of symmetry breaking due to th…
