  • Thermodynamic and hydrodynamic behaviour of interacting Fermi gases 

    Goulko, Olga (University of CambridgeDepartment of Applied Mathematics and Theoretical Physics, 2012-01-10)
    Fermionic matter is ubiquitous in nature, from the electrons in metals and semiconductors or the neutrons in the inner crust of neutron stars, to gases of fermionic atoms, like 40K or 6Li that can be created and studied ...

  • On some partial differential equation models in socio-economic contexts - analysis and numerical simulations 

    Pietschmann, Jan-Frederik (University of CambridgeDepartent of Applied Mathhematics and Theoretical PhysicsTrinity College, 2012-01-10)
    This thesis deals with the analysis and numerical simulation of different partial differential equation models arising in socioeconomic sciences. It is divided into two parts: The first part deals with a mean-field price ...

  • Dynamical instabilities in disc-planet interactions 

    Lin, Min-Kai (University of Cambridge, 2012-01-10)
    Protoplanetary discs can be dynamically unstable due to structure induced by an embedded giant planet. In this thesis, I discuss the stability of such systems and explore the consequence of instability on planetary ...

  • Turbulence ingestion noise of open rotors 

    Robison, Rosalyn Aruna Venner (University of CambridgeDepartment of Applied Mathematics and Theoretical Physics, 2012-04-10)
    Renewed interest in open rotor aeroengines, due to their fuel efficiency, has driven renewed interest in all aspects of the noise they generate. Noise due to the ingestion of distorted atmospheric turbulence, known as ...

  • Freeze fracturing of elastic porous media 

    Vlahou, Ioanna (University of CambridgeDepartment of Applied Mathematics and Theoretical PhysicsInstitute of Theoretical Geophysics, 2012-06-12)
    The physical motivation behind this thesis is the phenomenon of fracturing of rocks and other porous media due to ice growth inside pre-existing faults and large pores. My aim is to explain the basic physical processes ...

  • Variable selection with error control: Another look at Stability Selection 

    Shah, Rajen Dinesh; Samworth, Richard John (Wiley on behalf of the Royal Statistical SocietyJournal of the Royal Statistical Society: Series B (Statistical Methodology), 2012-06-21)
    Stability Selection was recently introduced by Meinshausen and B¨uhlmann (2010) as a very general technique designed to improve the performance of a variable selection algorithm. It is based on aggregating the results of ...

  • Differential systems, moving frames, structure-preserving submersions and geometrical problems in physics 

    Hu, Ziyang (University of CambridgeDepartment of Applied Mathematics and Theoretical Physics, 2012-07-03)
    The present work applies the theories of exterior differential systems, method of equivalence and moving frames to the study of geometrical problems arising in physics, especially the class of problems that can be described ...

  • Indices for Supersymmetric Quantum Field Theories in Four Dimensions 

    Ehrhardt, Mathieu (University of CambridgeDepartment of Applied Mathematics and Theoretical PhysicsTrinity Hall, 2012-07-21)
    In this thesis, we investigate four dimensional supersymmetric indices. The motivation for studying such objects lies in the physics of Seiberg's electric-magnetic duality in supersymmetric field theories. In the first ...

  • Optical conductivity with holographic lattices 

    Horowitz, GT; Santos, Jorge Eduardo; Tong, David (Journal of High Energy Physics, 2012-08-06)

  • 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 ...

  • On some nonlinear partial differential equations for classical and quantum many body systems 

    Marahrens, Daniel (University of CambridgeDepartment of Applied Mathematics and Theoretical PhysicsClare Hall, 2012-11-13)
    This thesis deals with problems arising in the study of nonlinear partial differential equations arising from many-body problems. It is divided into two parts: The first part concerns the derivation of a nonlinear diffusion ...

  • Dynamics of quasi-two-dimensional turbulent jets 

    Landel, Julien Rémy Dominique Gérard (University of CambridgeDepartment of Applied Mathematics and Theoretical PhysicsChurchill CollegeBP Institute, 2012-11-13)
    The study of quasi-two-dimensional turbulent jets is relevant to chemical reactors, the coking process in oil refinement, as well as rivers flowing into lakes or oceans. In the event of a spillage of pollutants into a ...
