Perturbing Gravitational Atoms: Negative Love, Resonant Tides and Shifted Resonances
Mateja Bošković, Nikola Savić
The superradiant instability of rotating black holes can generate a significant overdensity of bosonic matter around them, together forming a gravitational atom. This mechanism all…
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…
Weak chaos and mixed dynamics in the string S-matrix
Nikola Savić, Mihailo Čubrović
We investigate chaotic dynamics in tree-level S-matrices describing the scattering of tachyons, photons and gravitons on highly excited open and closed bosonic strings, motivated b…
Vanishing of Nonlinear Tidal Love Numbers of Schwarzschild Black Holes
Massimiliano Maria Riva, Luca Santoni, Nikola Savić +1
It is well known that asymptotically flat Schwarzschild black holes in general relativity in four spacetime dimensions have vanishing induced linear tidal response. We extend this…
