Hadamard States for the Vector Potential on Asymptotically Flat Spacetimes
Hadamard States Asymptotically Flat Spacetimes General Relativity and Quantum Cosmology

Abstract: We develop a quantization scheme for the vector potential on globally hyperbolic spacetimes which realizes it as a locally covariant conformal quantum field theory. This result allows us to ...
Local causal structures, Hadamard states and the principle of local covariance in quantum field theory
quantum field theory local covariance

In the framework of the algebraic formulation, we discuss and analyse some new features of the local structure of a real scalar quantum field theory in a strongly causal spacetime. In particular we us...
