Semiclassical gravity with a conformally covariant field in globally hyperbolic spacetimes
Benito A. Juárez-Aubry, Sujoy K. Modak
We prove that semiclassical gravity in conformally static, globally hyperbolic spacetimes with a massless, conformally coupled Klein-Gordon field is well posed, when viewed as a co…
Quantum kicks near a Cauchy horizon
Benito A. Juárez-Aubry, Jorma Louko
We analyse a quantum observer who falls geodesically towards the Cauchy horizon of a -dimensional eternal black hole spacetime with the global structure of the non-extremal…
What happens once an accelerating observer has detected a Rindler particle?
Angel Garcia-Chung, Benito A. Juárez-Aubry, Daniel Sudarsky
In a seminal paper, Unruh and Wald found that the detection of a right Rindler particle by a linearly uniformly accelerated detector coupled to a Klein-Gordon field in the Minkowsk…
Black Holes and the 2020 Nobel Prize in Physics
Yuri Bonder, Benito A. Juárez-Aubry
The 2020 Nobel Prize in Physics distinguished two research projects on black holes, which are one of the most striking predictions of General Relativity. The prize was divided in t…
Semiclassical gravity in static spacetimes as a constrained initial value problem
Benito A. Juárez-Aubry
We study the semiclassical Einstein field equations with a Klein-Gordon field in ultrastatic and static spacetimes. In both cases, the equations for the spacetime metric become con…
Asymptotic states for stationary Unruh-DeWitt detectors
Benito A. Juárez-Aubry, Dimitris Moustos
We study the late-time asymptotic state of a stationary Unruh-DeWitt detector interacting with a field in a thermal state. We work in an open system framework, where the field play…
Semi-classical gravity in de Sitter spacetime and the cosmological constant
Benito A. Juárez-Aubry
We show that there exist solutions to the semi-classical gravity equations in de Sitter spacetime sourced by the renormalised stress-energy tensor of a free Klein-Gordon field. For…
Mode solutions for a Klein-Gordon field in anti-de Sitter spacetime with dynamical boundary conditions of Wentzell type
Claudio Dappiaggi, Hugo R. C. Ferreira, Benito A. Juárez-Aubry
We study a real, massive Klein-Gordon field in the Poincaré fundamental domain of the -dimensional anti-de Sitter (AdS) spacetime, subject to a particular choice of dynamica…
Asymptotics in the time-dependent Hawking and Unruh effects
Benito A. Juárez-Aubry
In this thesis, we study the Hawking and Unruh effects in time-dependent situations, as registered by localised spacetimes observers in several asymptotic situations. (Full abstrac…
Generally covariant dynamical reduction models and the Hadamard condition
Benito A. Juárez-Aubry, Bernard S. Kay, Daniel Sudarsky
We provide general guidelines for generalizing dynamical reduction models to curved spacetimes and propose a class of generally covariant relativistic versions of the GRW model. We…
Waiting for Unruh
Christopher J. Fewster, Benito A. Juárez-Aubry, Jorma Louko
How long does a uniformly accelerated observer need to interact with a quantum field in order to record thermality in the Unruh temperature? We address this question for a pointlik…
Can a particle detector cross a Cauchy horizon?
Benito A. Juárez-Aubry
Cauchy horizons are well known to exhibit instabilities in classical spacetime dynamics and singularities in quantum field theory. We analyse the response of an Unruh-DeWitt partic…
Onset and decay of the 1+1 Hawking-Unruh effect: what the derivative-coupling detector saw
Benito A. Juárez-Aubry, Jorma Louko
We study an Unruh-DeWitt particle detector that is coupled to the proper time derivative of a real scalar field in 1+1 spacetime dimensions. Working within first-order perturbation…
