Black Hole Dynamics at Fifth Post-Newtonian Order
Rafael A. Porto, Massimiliano M. Riva
Using the worldline action in [2409.05860], we derive the total even-in-velocity (relative) impulse, scattering angle, and time delay at fifth post-Newtonian (5PN) order, including…
Nonlinear Relativistic Tidal Response of Neutron Stars
Paolo Pani, Massimiliano Maria Riva, Luca Santoni +2
We investigate the nonlinear tidal response of relativistic neutron stars by computing the fully relativistic, static, quadratic Love numbers. Using both the worldline effective fi…
Vanishing of Quadratic Love Numbers of Schwarzschild Black Holes
Simon Iteanu, Massimiliano Maria Riva, Luca Santoni +2
The induced conservative tidal response of self-gravitating objects in general relativity is parametrized in terms of a set of coefficients, which are commonly referred to as Love…
Nonlinear Gravitational Radiation Reaction: Failed Tail, Memories & Squares
Rafael A. Porto, Massimiliano M. Riva, Zixin Yang
Using the Schwinger-Keldysh "in-in" effective field theory (EFT) framework, we complete the knowledge of nonlinear gravitational radiation-reaction effects in the (relative) dynami…
