Quantum superposition of boundary condition in

João P. M. Pitelli, Bruno S. Felipe, Claudio Dappiaggi +1

We explore the quantum superposition of boundary conditions in the context of the Poincaré patch of the two-dimensional Anti-de Sitter space (). Focusing on Robin…

Renormalized stress-energy tensor on global anti-de Sitter space-time with Robin boundary conditions

Thomas Morley, Sivakumar Namasivayam, Elizabeth Winstanley

We study the renormalized stress-energy tensor (RSET) for a massless, conformally coupled scalar field on global anti-de Sitter space-time in four dimensions. Robin (mixed) boundar…

Superradiance and quantum states on black hole space-times

Visakan Balakumar, Rafael Bernar, Elizabeth Winstanley

We consider the definition of the Boulware and Hartle-Hawking states for quantum fields on black hole space-times. The properties of these states on a Schwarzschild black hole have…

Charge superradiance on charged BTZ black holes

Sebastian Konewko, Elizabeth Winstanley

We study superradiant scattering for a charged scalar field subject to Robin (mixed) boundary conditions on a charged BTZ black hole background. Scalar field modes having a real fr…

Vacuum polarization on three-dimensional anti-de Sitter space-time with Robin boundary conditions

Sivakumar Namasivayam, Elizabeth Winstanley

We study a quantum scalar field, with general mass and coupling to the scalar curvature, propagating on three-dimensional global anti-de Sitter space-time. We determine the vacuum…

Equivalence of the adiabatic expansion and Hadamard renormalization for a charged scalar field

Silvia Pla, Elizabeth Winstanley

We examine the relationship between three approaches (Hadamard, DeWitt-Schwinger and adiabatic) to the renormalization of expectation values of field operators acting on a charged…
