| Syllabus 1) Surface charges in general relativity - the notion of total energy in general relativity - an instructive example: surface charges in 3D gravity - the covariant phase-space formalism - surface charges in generally covariant field theories - asymptotically flat spacetimes and BMS symmetry 2) Gravitational observables from scattering amplitudes - eikonal phase and deflection angle - memory effect from the leading soft graviton theorem - soft limit of the energy spectrum, static angular momentum loss Reading suggestions [1] Wald, "General Relativity," The University of Chicago Press, 1984 [2] Campoleoni, Fredenhagen, "Higher-spin gauge theories in three space-time dimensions," arXiv:2312.xxxxx.
