  • Aspects of higher dimensional Einstein theory and M-theory 

    Godazgar, Mohammad Mahdi (University of CambridgeDepartment of Applied Mathematics and Theoretical Physics, 2012-10-09)
    This thesis contains two main themes. The first is Einstein's theory of general relativity in higher dimensions, while the second is M-theory. The first part of the thesis concerns the use of classification techniques ...

  • Constrained dynamics and higher derivative systems in modified gravity 

    Chen, Tai-jun (University of CambridgeDepartment of Applied Mathematics and Theoretical Physics, 2015-06-09)
    In this thesis, higher derivative theories and constrained dynamics are investigated in detail. In the first part of the thesis, we discuss how the Ostrogradski instability emerges in non-degenerate higher derivative ...

  • Graphical representations of Ising and Potts models: stochastic geometry of the quantum Ising model and the space-time Potts model 

    Björnberg, Jakob Erik (University of CambridgeDepartment of Pure Mathematics and Mathematical StatisticsStatistical LaboratoryGonville & Caius College, 2010-02-09)
    Statistical physics seeks to explain macroscopic properties of matter in terms of microscopic interactions. Of particular interest is the phenomenon of phase transition: the sudden changes in macroscopic properties as ...

  • New approaches to higher-dimensional general relativity 

    Durkee, Mark N. (University of CambridgeDepartment of Applied Mathematics and Theoretical Physics, 2011-06-07)
    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 ...

  • Symmetric structures in Banach spaces
