Dynamical Love Numbers for Black Holes and Beyond from Shell Effective Field Theory
Dimitrios Kosmopoulos, Davide Perrone, Mikhail Solon
We construct a novel effective field theory for a compact body coupled to gravity, whose key feature is that the dynamics of gravitational perturbations is explicitly determined by…
Observables and Unconstrained Spin Tensor Dynamics in General Relativity from Scattering Amplitudes
Mark Alaverdian, Zvi Bern, Dimitrios Kosmopoulos +4
In a previous Letter, we showed that physical scattering observables for compact spinning objects in general relativity can depend on additional degrees of freedom in the spin tens…
Conservative Spin Magnitude Change in Orbital Evolution in General Relativity
Mark Alaverdian, Zvi Bern, Dimitrios Kosmopoulos +4
We show that physical scattering observables for compact spinning objects in general relativity can depend on additional degrees of freedom in the spin tensor beyond those describe…
Gravitational Self Force from Scattering Amplitudes in Curved Space
Dimitrios Kosmopoulos, Mikhail P. Solon
We employ scattering amplitudes in curved space to model the dynamics of a light probe particle with mass orbiting in the background spacetime induced by a heavy gravitational…
Quantum Field Theory, Worldline Theory, and Spin Magnitude Change in Orbital Evolution
Zvi Bern, Dimitrios Kosmopoulos, Andres Luna +4
A previous paper~\cite{Bern:2022kto} identified a puzzle stemming from the amplitudes-based approach to spinning bodies in general relativity: additional Wilson coefficients appear…
Effective Field Theory Islands from Perturbative and Nonperturbative Four-Graviton Amplitudes
Zvi Bern, Enrico Herrmann, Dimitrios Kosmopoulos +1
Theoretical data obtained from physically sensible field and string theory models suggest that gravitational Effective Field Theories (EFTs) live on islands that are tiny compared…
Binary Dynamics Through the Fifth Power of Spin at
Zvi Bern, Dimitrios Kosmopoulos, Andrés Luna +2
We use a previously developed scattering-amplitudes-based framework for determining two-body Hamiltonians for generic binary systems with arbitrary spin . By construction this f…
Gravitational Effective Field Theory Islands, Low-Spin Dominance, and the Four-Graviton Amplitude
Zvi Bern, Dimitrios Kosmopoulos, Alexander Zhiboedov
We analyze constraints from perturbative unitarity and crossing on the leading contributions of higher-dimension operators to the four-graviton amplitude in four spacetime dimensio…
Quadratic-in-Spin Hamiltonian at from Scattering Amplitudes
Dimitrios Kosmopoulos, Andres Luna
We obtain the quadratic-in-spin terms of the conservative Hamiltonian describing the interactions of a binary of spinning bodies in General Relativity through an…
Simplifying -Dimensional Physical-State Sums in Gauge Theory and Gravity
Dimitrios Kosmopoulos
We provide two independent systematic methods of performing -dimensional physical-state sums in gauge theory and gravity in such a way so that spurious light-cone singularities…
