On a Recent Construction of "Vacuum-like" Quantum Field States in Curved Spacetime
Christopher J. Fewster, Rainer Verch
Afshordi, Aslanbeigi and Sorkin have recently proposed a construction of a distinguished "S-J state" for scalar field theory in (bounded regions of) general curved spacetimes. We e…

Quantization of linearized gravity in cosmological vacuum spacetimes
Christopher J. Fewster, David S. Hunt
Linearized Einstein gravity (with possibly nonzero cosmological constant) is quantized in the framework of algebraic quantum field theory by analogy with Dimock's treatment of elec…

Endomorphisms and automorphisms of locally covariant quantum field theories
Christopher J. Fewster
In the framework of locally covariant quantum field theory, a theory is described as a functor from a category of spacetimes to a category of *-algebras. It is proposed that the gl…
