Dirac brackets for classical radiative observables
Francesco Alessio, Riccardo Gonzo, Canxin Shi
We introduce a new coherent state expansion of the exponential representation of the S-matrix for the classical gravitational two-body problem. By combining the Kosower-Maybee-O'Co…

Logarithmic soft theorems and soft spectra
Francesco Alessio, Paolo Di Vecchia, Carlo Heissenberg
Using universal predictions provided by classical soft theorems, we revisit the energy emission spectrum for gravitational scatterings of compact objects in the low-frequency expan…

Infrared gravity and a celestial obstruction to monogamy constraints
Francesco Alessio, Michele Arzano
We argue that gravitational interactions between particles require a departure from the conventional picture of the quantum state of a multiparticle system in terms of tensor produ…
