Radiation-reaction driven dynamics at the third-and-a-half post-Newtonian order in different gauges
Donato Bini, Andrea Geralico, Sara Rufrano Aliberti
We consider the coordinate-dependent definition of the radiation-reaction force at the third-and-a-half post-Newtonian order for general orbits. In order to (partially) determine i…
Asymptotic Safety in Generalized Proca Theories
Lavinia Heisenberg, Alessia Platania, Sara Rufrano Aliberti
Generalized Proca Theories are the most general higher-derivative extensions of a massive vector field that retain second-order equations of motion. They are phenomenologically int…
Radiation-reaction correction to scattering binary dynamics at the Next-to-Leading Post-Newtonian Order
Donato Bini, Andrea Geralico, Sara Rufrano Aliberti
We compute the next-to-leading-order radiation-reaction modification to the harmonic coordinate quasi-Keplerian parametrization of the binary dynamics, the two bodies undergoing a…
Limits on dark matter, ultralight scalars, and cosmic neutrinos with gyroscope spin and precision clocks
Sara Rufrano Aliberti, Gaetano Lambiase, Tanmay Kumar Poddar
Dark matter (DM) within the solar system induces deviations in the geodetic drift of gyroscope spin due to its gravitational interaction. Assuming a constant DM density as a minima…
