High-order expansions of the Detweiler-Whiting singular field in Kerr spacetime
Anna Heffernan, Adrian Ottewill, Barry Wardell
In a previous paper, we computed expressions for the Detweiler-Whiting singular field of point scalar, electromagnetic and gravitational charges following a geodesic of the Schwarz…
Analytic Investigation of the Branch Cut of the Green Function in Schwarzschild Space-time
Marc Casals, Adrian C. Ottewill
The retarded Green function for linear field perturbations in Schwarzschild black hole space-time possesses a branch cut in the complex-frequency plane. This branch cut has remaine…
Quantum field theory on the Bertotti-Robinson space-time
Adrian C. Ottewill, Peter Taylor
We consider the problem of quantum field theory on the Bertotti-Robinson space-time, which arises naturally as the near horizon geometry of an extremal Reissner-Nordstrom black hol…
Kermions: quantization of fermions on Kerr space-time
Marc Casals, Sam R. Dolan, Brien C. Nolan +2
We study a quantum fermion field on a background non-extremal Kerr black hole. We discuss the definition of the standard black hole quantum states (Boulware, Unruh and Hartle-Hawki…
Regularization of static self-forces
Marc Casals, Eric Poisson, Ian Vega
Various regularization methods have been used to compute the self-force acting on a static particle in a static, curved spacetime. Many of these are based on Hadamard's two-point f…
Static Kerr Green's Function in Closed Form and an Analytic Derivation of the Self-Force for a Static Scalar Charge in Kerr Space-Time
Adrian C. Ottewill, Peter Taylor
We derive a closed-form solution for the Green's function for the wave equation of a static (with respect to an undragged, static observer at infinity) scalar charge in the Kerr sp…
