Gravitational Memory Beyond Null Infinity through Finite-Distance Carrollian Screens
Felipe Diaz, Sercan Hüsnügil, Oriana Labrin +1
We investigate gravitational memory beyond null infinity by studying finite-distance null hypersurfaces endowed with Carrollian geometry. We show that the intrinsic degenerate geom…

Asymptotic structure of scalar-Maxwell theory at the null boundary
Hernán A. González, Oriana Labrin, Olivera Miskovic
We apply the Hamiltonian formalism to investigate the massless sector of scalar field theory coupled with Maxwell electrodynamics through the Pontryagin term. Specifically, we anal…

Kac-Moody symmetry in the light front of gauge theories
Hernán A. González, Oriana Labrin, Olivera Miskovic
We discuss the emergence of a new symmetry generator in a Hamiltonian realisation of four-dimensional gauge theories in the flat space foliated by retarded (advanced) time. It gene…
