Second-order scattering response of a Schwarzschild black hole
Bruno Bucciotti, Jaime Redondo-Yuste, Adrien Kuntz +2
Gravitational waves couple in a nonlinear fashion in the vicinity of a black hole. Black hole perturbation theory can be readily applied to compute the magnitude of this coupling,…
On the Asymptotic Causal Structure in Gravitational EFTs
Bruno Bucciotti, Paolo Creminelli, Alessandro Longo +2
It is usually assumed that a healthy EFT should not allow superluminal propagation. In the presence of gravity, however, the notion of superluminality becomes subtle, since there i…
Unraveling the Spectrum of the Open String
Bruno Bucciotti, Felipe Figueroa, Guilherme L. Pimentel
We construct a large portion of the massive spectrum of the open bosonic string using light-cone quantization, providing explicit oscillator realizations for individual single-part…
Black hole spectroscopy: from theory to experiment
Emanuele Berti, Vitor Cardoso, Gregorio Carullo +65
The "ringdown" radiation emitted by oscillating black holes has great scientific potential. By carefully predicting the frequencies and amplitudes of black hole quasinormal modes a…
Ringdown nonlinearities in the eikonal regime
Bruno Bucciotti, Vitor Cardoso, Adrien Kuntz +2
The eikonal limit of black hole quasinormal modes (the large multipole limit ) can be realized geometrically as a next-to-leading order solution to the geometric optics…
A Note on the Existence of Equal Time Correlators
Bruno Bucciotti
The Schroedinger picture, which underpins the Wavefunction of the Universe framework to compute Cosmological Correlators, is known to be generically problematic in QFT because of t…
The Monopole-Fermion Problem in a Chiral Gauge Theory (the Model)
Stefano Bolognesi, Bruno Bucciotti, Andrea Luzio
The scattering of electrically charged fermions on magnetic monopole leads to the Callan-Rubakov problem. We discuss some aspects of this problem for Abelian gauge theories with ch…
Amplitudes and Polarizations of Quadratic Quasi-Normal Modes for a Schwarzschild Black Hole
Bruno Bucciotti, Leonardo Juliano, Adrien Kuntz +1
General Relativity predicts the existence of quadratic quasi-normal modes at second order in perturbation theory. Building on our recent work, we compute the amplitudes and polariz…
Quadratic Quasi-Normal Modes of a Schwarzschild Black Hole
Bruno Bucciotti, Leonardo Juliano, Adrien Kuntz +1
Quadratic quasi-normal modes, generated at second order in black hole perturbation theory, are a promising target for testing gravity in the nonlinear regime with next-generation g…
A note on Gauss operators and quantizations of Yang-Mills theories
Bruno Bucciotti, Franco Strocchi
The quantization of Yang-Mills field theories requires the introduction of a gauge fixing which leads to a violation of the Local Gauss Law described by the so-called Gauss operato…
Nonlinear Quasi-Normal Modes: Uniform Approximation
Bruno Bucciotti, Adrien Kuntz, Francesco Serra +1
Recent works have suggested that nonlinear (quadratic) effects in black hole perturbation theory may be important for describing a black hole ringdown. We show that the technique o…
An anharmonic alliance: exact WKB meets EPT
Bruno Bucciotti, Tomas Reis, Marco Serone
Certain quantum mechanical systems with a discrete spectrum, whose observables are given by a transseries in , were shown to admit -deformations with Borel resummab…
Interplay between Black Holes and Ultralight Dark Matter: Analytic Solutions
Bruno Bucciotti, Enrico Trincherini
Dark matter (DM) can consist of a scalar field so light that DM particles in the galactic halo are best described by classical waves. We investigate how these classical solutions a…
