Correction to: The Double-Wedge Algebra for Quantum Fields on Schwarzschild and Minkowski Spacetimes
Bernard S. Kay
There is an error in the proof (but not the truth) of Theorem 3.2 in the author's 1985 paper "The Double-Wedge Algebra for Quantum Fields on Schwarzschild and Minkowski Spacetimes"…
The Hadamard condition on a Cauchy surface and the renormalized stress-energy tensor
Benito A. Juárez-Aubry, Bernard S. Kay, Tonatiuh Miramontes +1
Given a Cauchy surface in a curved spacetime and a suitably defined quantum state on the CCR algebra of the Klein-Gordon quantum field on that surface, we show, by expanding the sq…
Quantum Field Theory in Curved Spacetime (2nd Edition)
Bernard S. Kay
The 2023 second edition of a 2006 encyclopedia article on mathematical aspects of quantum field theory in curved spacetimes (QFTCST). Section-titles (with new sections indicated wi…
Matter-gravity entanglement entropy and the second law for black holes
Bernard S. Kay
Hawking showed that a black hole formed by collapse will emit radiation and eventually disappear. We address the challenge to define an objective notion of physical entropy which i…
The black hole information loss puzzle, matter-gravity entanglement entropy and the second law
Bernard S. Kay
Since Hawking's 1974 discovery, we expect that a black hole formed by collapse will emit radiation and eventually disappear. Closely related to the information loss puzzle is the c…
On the initial value problem for semiclassical gravity without and with quantum state collapses
Benito A. Juárez-Aubry, Bernard S. Kay, Tonatiuh Miramontes +1
We explore how the initial value problem may be formulated for globally hyperbolic, Hadamard, solutions of the semiclassical Einstein-Klein-Gordon equations. Given a set of data on…
