Are inertial vacua equivalent in Lorentz-violating theories? Does it matter?
Bruno Arderucio Costa, Yuri Bonder, Benito A. Juárez-Aubry
Several approaches to quantum gravity suggest violations of Lorentz symmetry as low-energy signatures. This article uses a concrete Lorentz-violating quantum field theory to study…
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…
Ground State for the Klein-Gordon field in anti-de Sitter spacetime with dynamical Wentzell boundary conditions
Claudio Dappiaggi, Benito A. Juárez-Aubry, Alessio Marta
We consider a real Klein-Gordon field in the Poincaré patch of -dimensional anti-de Sitter spacetime, PAdS, and impose dynamical boundary condition on the asymptotic…
Boundary Hilbert spaces and trace operators
J. Fernando G. Barbero, Benito A. Juárez-Aubry, Juan Margalef-Bentabol +1
We discuss the introduction of boundary Hilbert spaces for a class of physical systems for which it is not possible to factor their state spaces as tensor products of Hilbert space…
Quantization of scalar fields coupled to point-masses
J. Fernando Barbero, Benito A. Juárez-Aubry, Juan Margalef-Bentabol +1
We study the Fock quantization of a compound classical system consisting of point masses and a scalar field. We consider the Hamiltonian formulation of the model by using the geome…
