The robustness of a many-body decoherence formula of Kay under changes in graininess and shape of the bodies
Varqa Abyaneh, Bernard S. Kay
In ``Decoherence of macroscopic closed systems within Newtonian quantum gravity'' (Kay B S 1998 Class. Quantum Grav. 15 L89-L98) it was argued that, given a many-body Schroedinger…

Application of linear hyperbolic PDE to linear quantum fields in curved spacetimes: especially black holes, time machines and a new semi-local vacuum concept
Bernard S. Kay
Several situations of physical importance may be modelled by linear quantum fields propagating in fixed spacetime-dependent classical background fields. For example, the quantum Di…

Quantum Fields in Curved Spacetime: Non Global Hyperbolicity and Locality
Bernard S. Kay
We briefly review the current status of the algebraic approach to quantum field theory on globally hyperbolic spacetimes, both axiomatic -- for general field theories, and construc…
