Quantum effects of charged massive scalar fields on charged black hole space-times
Cormac Breen, George Montagnon, Peter Taylor +1
We compute the renormalized expectation values of the scalar condensate, charge current and stress-energy tensor for a massive charged quantum scalar field on a Reissner-Nordstrom…
Quantum-corrected three-dimensional AdS space-time
Jacob C. Thompson, Elizabeth Winstanley
We study quantum-corrected solitons in global, three-dimensional, anti-de Sitter (AdS) space-time. These static solitons have a regular origin and arise as solutions of the lineari…
Quantum effects in rotating thermal states on anti-de Sitter space-time
Jacob C. Thompson, Elizabeth Winstanley
We study the stress-energy tensor of a massless, conformally coupled, quantum scalar field in a rigidly-rotating thermal state on three- and four-dimensional anti-de Sitter space-t…
Renormalized charged scalar current on a Reissner-Nordstrom black hole in the presence of charge superradiance
George Montagnon, Elizabeth Winstanley
We compute the renormalized charge current for a massless, minimally coupled, charged quantum scalar field on a charged Reissner-Nordstrom black hole space-time, using the method o…
Nonminimal coupling, quantum scalar field stress-energy tensor and energy conditions on global anti-de Sitter space-time
Sivakumar Namasivayam, Elizabeth Winstanley
We compute the renormalized expectation value of the stress-energy tensor operator for a quantum scalar field propagating on three-dimensional global anti-de Sitter space-time. The…
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…
Kermions
Elizabeth Winstanley
In the framework of quantum field theory in curved space-time, we study the quantization of a massless fermion field on a non-extremal Kerr black hole. The key theme in this note i…
