Gravitational amplitudes in the Regge limit: waveforms, shock waves and unitarity cuts
Francesco Alessio, Vittorio Del Duca, Riccardo Gonzo +1
Motivated by recent progress in the high-energy description of gravitational scattering, we develop a systematic Regge-theory framework for amplitudes describing the scat…
Analytic structure of the high-energy gravitational amplitude: multi-H diagrams and classical 5PM logarithms
Francesco Alessio, Vittorio Del Duca, Riccardo Gonzo +3
We investigate the high-energy, small-angle limit of two-body gravitational scattering. Using power counting arguments and dispersion relations in an effective field theory for the…
Searching for Kerr in string amplitudes
Francesco Alessio, Paolo Di Vecchia, Maurizio Firrotta +1
We continue the approach of [1] to attempt to reproduce the classical electromagnetic current of the solution from the infinite-spin limit of a three-point a…
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…
A new pairwise boost quantum number from celestial states
Francesco Alessio, Michele Arzano
Infrared effects in the scattering of particles in gravity and electrodynamics entail an exchange of relativistic angular momentum between pairs of particles and the gauge field. D…
2PM waveform from loop corrected soft theorems
Francesco Alessio, Paolo Di Vecchia
We introduce a classical version of the loop corrected soft graviton theorem and we use it to compute the universal part of the one-loop (2PM) waveform up to sub-subleading order i…
Kerr binary dynamics from minimal coupling and double copy
Francesco Alessio
We construct a new Yang-Mills Lagrangian based on a notion of minimal coupling that incorporates classical spin effects. The construction relies on the introduction of a new covari…
Notes on massless scalar field partition functions, modular invariance and Eisenstein series
Francesco Alessio, Glenn Barnich, Martin Bonte
The partition function of a massless scalar field on a Euclidean spacetime manifold and with momentum operator in the compact spatial dimension…
Gravitons in a Casimir box
Francesco Alessio, Glenn Barnich, Martin Bonte
The partition function of gravitons with Casimir-type boundary conditions is worked out. The simplest box that allows one to achieve full analytical control consists of a slab geom…
Weyl Charges in Asymptotically Locally AdS Spacetimes
Francesco Alessio, Glenn Barnich, Luca Ciambelli +2
We discuss an enhancement of the Brown-Henneaux boundary conditions in three-dimensional AdS General Relativity to encompass Weyl transformations of the boundary metric. The result…
Modular invariance in finite temperature Casimir effect
Francesco Alessio, Glenn Barnich
The temperature inversion symmetry of the partition function of the electromagnetic field in the set-up of the Casimir effect is extended to full modular transformations by turning…
Note on the symplectic structure of asymptotically flat gravity and BMS symmetries
Francesco Alessio, Michele Arzano
The Poisson brackets of the gravitational field at null infinity play a pivotal role in establishing the equivalence between the Ward identities involving BMS charges and the soft…
A fuzzy bipolar celestial sphere
Francesco Alessio, Michele Arzano
We introduce a non-commutative deformation of the algebra of bipolar spherical harmonics supporting the action of the full Lorentz algebra. Our construction is close in spirit to t…
From parabolic to loxodromic BMS transformations
Giampiero Esposito, Francesco Alessio
Half of the Bondi-Metzner-Sachs (BMS) transformations consist of orientation-preserving conformal homeomorphisms of the extended complex plane known as fractional linear (or Mobius…
Asymptotic Structure and Bondi-Metzner-Sachs group in General Relativity
Francesco Alessio
In this work the asymptotic structure of space-time and the main properties of the Bondi-Metzner-Sachs (BMS) group, which is the asymptotic symmetry group of asymptotically flat sp…
On the structure and applications of the Bondi-Metzner-Sachs group
Francesco Alessio, Giampiero Esposito
This work is a pedagogical review dedicated to a modern description of the Bondi-Metzner-Sachs group. The curved space-times that will be taken into account are the ones that suita…
