In this project, the theory of self-adjoint extensions of symmetric operators will be applied to semiclassical gravity and quantum cosmology. My main interests are in the resolution, via quantum gravity, of the classical singularities in General Relativity, both in static spacetimes and in cosmological models. I am also interested in the stability/instability of spacetimes according to t…
In this undergraduate research project, the concept of non-globally hyperbolic space-times will be introduced to the student through the study of wave's propagation in an asymptotically anti-de Sitter background. The study will be guided by the advisor's and his collaborators' article published recently in the periodic "Journal of Mathematical Physics" [1]. The main goal of this article,…
In this project, the student will be introduced to the Hamiltonian formalism of General Relativity through a cosmological model. In order to achieve this goal, the student will study the Arnowitt-Deser-Misner decomposition of space-time and the Hamiltonian formalism of a perfect fluid coupled to gravity. In this way, the student will find and solve Friedmann equations from a different per…
In this project, the applicant will study quantum field theory in curved spaces through the concept of quantum singularities. In this way, the propagation of quantum fields in classically singular space times will be studied, in order to understand the concept of singularity of a space time when tested by quantum particles.
We will study some aspects of quantum cosmology on the theory of Horava-Lifshitz, for example the Friedmann-Robertson-Walker universe filled with a perfect fluid. We will also study the influence that vacuum fluctuations have on the light cone, in a 2-dimensional model of gravitation with a dilaton field. (AU)

It is well known that in globally-hyperbolic spacetimes the evolution of quantum fields is uniquely determined by the initial conditions on a Cauchy hypersurface. This is not the case for non-globally hyperbolic spacetimes. For instance, in spacetimes with a naked singularity, the quantum field may interact in a non-trivial way with the singularity. Similarly, in asymptotically AdS space…
We will study the physical effects due to the arbitrariness on the choice of the boundary conditions at the spatial boundary in non-globally-hyperbolic spaces. Our aim is to analyse how is the bath of particles that one observer in a particular vacuum (corresponding to a particular bondary condition) receives from another vacuum (cor- responding to a different boundary condition). We expe…
