    Teixeira da Costa, RitaUniversity of Cambridge2021

    … problem for the vacuum Einstein equations in General Relativity. The common theme is the use of frequency analysis as a tool to exploit fine structures within the partial differential equations. However, the two parts are structured so as to be read independently. The first part concerns the …

  6. Quantum information and thermodynamics of general relativity

    Μούστος, Δημήτριος2020

    We treat an Unruh-DeWitt detector as an open quantum system, with a quantum field playing the role of the environment, and evaluate the response of a uniformly accelerated detector for different types of interaction between the detector and the field. We derive the evolution equations for the …

  7. Negative Point Mass Singularities in General Relativity

    Robbins, Nicholas Philip2007

    First we review the definition of a negative point mass singularity. Then we examine the gravitational lensing effects of these singularities in isolation and with shear and convergence from continuous matter. We review the Inverse Mean Curvature Flow and use this flow to prove some new results …

  9. New approaches to higher-dimensional general relativity

    Durkee, Mark N.University of Cambridge2011

    This thesis considers various aspects of general relativity in more than four spacetime dimensions. Firstly, I review the generalization to higher dimensions of the algebraic classification of the Weyl tensor and the Newman-Penrose formalism. In four dimensions, these techniques have proved useful …

  10. Numerical simulations of instabilities in general relativity

    Kunesch, MarkusUniversity of Cambridge2018

    General relativity, one of the pillars of our understanding of the universe, has been a remarkably successful theory. It has stood the test of time for more than 100 years and has passed all experimental tests so far. Most recently, the LIGO collaboration made the first-ever direct detection of …

This method uses the (1+3)-covariant formalism to establish the consistency of the Einstein gravitational field equations under the barotropic shear-free perfect fluid condition. Using a Mathematica package xTensor, we were able …

    This thesis is concerned with several problems in general relativity and low energy string theory that are pertinent to the time evolution of the gravitational field. We present a formulation of the Einstein field equations in terms of variational techniques borrowed from geometric analysis. These …
