High-order gravitational late-time tails in Kerr spacetime
Marc Casals, Chris Kavanagh, Jakob Neef +1
The paper derives analytic high‑order late‑time decay tails of the retarded Green’s function for linear field perturbations in subextremal Kerr spacetime, giving explicit power‑law…
Vacuum polarization and renormalized stress-energy tensor of spherical thin shells
Julio Arrechea, Cormac Breen, Adrian Ottewill +2
We provide a thorough study of the properties of the Boulware vacuum in the spacetime of a spherical, static thin shell with a Minkowski interior. To this end, we calculate the ren…
Quantum fluxes and for a non-minimally coupled scalar field: ringdown and tail on approaching the polar Kerr inner horizon
Maria Alberti, Noa Zilberman, Marc Casals +1
We compute as well as the energy fluxes and (where and $…
Post-Newtonian expansion of fluxes from a scalar charge on an inclined-spherical orbit about a Kerr black hole
Jezreel C. Castillo, Charles R. Evans, Chris Kavanagh +3
Efforts are underway to accurately model extreme-mass-ratio inspirals for binaries with a spinning (Kerr) primary. At lowest order the adiabatic evolution depends on the radiation…
Computation of and quantum fluxes at the polar interior of a spinning black hole
Noa Zilberman, Marc Casals, Adam Levi +2
Renormalization of physical quantities for quantum field theories in curved spacetimes can be achieved via the consistent subtraction of counterterms within a regularization scheme…
The renormalized stress-energy tensor for scalar fields in the Boulware state with applications to extremal black holes
Julio Arrechea, Cormac Breen, Adrian Ottewill +2
We provide a mode-sum prescription to directly compute the renormalized stress-energy tensor (RSET) for scalar fields in the Boulware vacuum. The method generalizes the recently de…
