Dynamical Tidal Response of Kerr Black Holes from Scattering Amplitudes
M. V. S. Saketh, Zihan Zhou, Mikhail M. Ivanov
We match scattering amplitudes in point particle effective field theory (EFT) and general relativity to extract low frequency dynamical tidal responses of rotating (Kerr) black hol…

Vanishing of black hole tidal Love numbers from scattering amplitudes
Mikhail M. Ivanov, Zihan Zhou
We extract the black hole (BH) static tidal deformability coefficients (Love numbers) and their spin-0 and spin-1 analogs by comparing on-shell amplitudes for fields to scatter off…

Revisiting the matching of black hole tidal responses: a systematic study of relativistic and logarithmic corrections
Mikhail M. Ivanov, Zihan Zhou
The worldline effective field theory (EFT) gives a gauge-invariant definition of black hole conservative tidal responses (Love numbers), dissipation numbers, and their spin-0 and s…
