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…
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…
Semiclassical theories as initial value problems
Benito A. Juárez-Aubry, Tonatiuh Miramontes, Daniel Sudarsky
Motivated by the initial value problem in semiclassical gravity, we study the initial value problem of a system consisting of a quantum scalar field weakly interacting with a class…
