On Instantons at Large Charge
Andrea Cipriani, Raffaele Savelli
The large R-charge limit of two-point functions of chiral primary operators in rank-one superconformal field theories exhibits a universal behavior controlled by th…
From the confluent Heun equation to a new factorized and resummed gravitational waveform for circularized, nonspinning, compact binaries
Andrea Cipriani, Alessandro Nagar, Francesco Fucito +1
We introduce a new factorized and resummed waveform for circularized, nonspinning, compact binaries that leverages on the solution of the Teukolsky equation once mapped into a conf…
"Waveforms" at the Horizon
Andrea Cipriani, Francesco Fucito, Carlo Heissenberg +2
We study perturbations induced by a light particle scattering off a Schwarzschild black hole. Exploiting recent results for the wave propagation in this geometry, we derive the fie…
Hamiltonian Neural Networks approach to fuzzball geodesics
Andrea Cipriani, Alessandro De Santis, Giorgio Di Russo +2
The recent increase in computational resources and data availability has led to a significant rise in the use of Machine Learning (ML) techniques for data analysis in physics. Howe…
Resumming Post-Minkowskian and Post-Newtonian gravitational waveform expansions
Andrea Cipriani, Giorgio Di Russo, Francesco Fucito +3
We derive formulae that resum, at a given order in the soft limit, the infinite series of Post-Minkowskian (small gravitational coupling) or Post-Newtonian (small velocities) corre…
Charge (in)stability and superradiance of Topological Stars
Andrea Cipriani, Carlo Di Benedetto, Giorgio Di Russo +2
We study linear massive scalar charged perturbations of Topological Stars in the fuzzball and in the black hole (Black String) regimes. The objects that naturally couple to the ele…
