Quantum scalar field theory on equal-angular-momenta Myers-Perry-AdS black holes
Alessandro Monteverdi, Elizabeth Winstanley
We study the canonical quantization of a massive scalar field on a five dimensional, rotating black hole space-time. We focus on the case where the space-time is asymptotically ant…
Quantum fermion superradiance and vacuum ambiguities on charged black holes
Álvaro Álvarez-Domínguez, Elizabeth Winstanley
Unlike a classical charged bosonic field, a classical charged fermion field on a static charged black hole does not exhibit superradiant scattering. We demonstrate that the quantum…
Some addition theorems for spin-weighted spherical harmonics
Alessandro Monteverdi, Elizabeth Winstanley
We present some addition theorems for spin-weighted spherical harmonics, generalizing previous results for scalar (spin-zero) spherical harmonics. These addition theorems involve s…
Mode-sum prescription for renormalized expectation values for a charged quantum scalar field on a charged black hole
Cormac Breen, George Montagnon, Peter Taylor +1
We present a new mode-sum prescription for the efficient computation of renormalized expectation values for a massive, charged, quantum scalar field propagating on a curved space-t…
Quantum-corrected anti-de Sitter space-time
Jacob C. Thompson, Elizabeth Winstanley
We study the back-reaction of a quantum scalar field on anti-de Sitter (AdS) space-time. The renormalized expectation value of the stress-energy tensor operator for a massless, con…
