Hadamard Renormalization of the Stress Energy Tensor in a Spherically Symmetric Black Hole Space-Time with an Application to Lukewarm Black Holes
Cormac Breen, Adrian C. Ottewill
We consider a quantum field which is in a Hartle-Hawking state propagating in a spherically symmetric black hole space-time. We calculate the components of the stress tensor, renor…
The Branch Cut and Quasi-normal Modes at Large Imaginary Frequency in Schwarzschild Space-time
Marc Casals, Adrian C. Ottewill
The 'retarded' Green function for fields propagating on a Schwarzschild black hole spacetime possesses a branch cut on the complex frequency plane. Classically, the branch cut is i…
Hadamard Renormalisation of the Stress Energy Tensor on the Horizons of a Spherically Symmetric Black Hole Space-Time
Cormac Breen, Adrian C. Ottewill
We consider a quantum field which is in a Hartle-Hawking state propagating in a general spherically symmetric black hole space-time. We make use of uniform approximations to the ra…
Wave Propagation and Quasinormal Mode Excitation on Schwarzschild Spacetime
Sam R. Dolan, Adrian C. Ottewill
To seek a deeper understanding of wave propagation on the Schwarzschild spacetime, we investigate the relationship between (i) the lightcone of an event and its caustics (self-inte…
