On some nonlinear partial differential equations for classical and quantum many body systems
(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 ...
Turbulence ingestion noise of open rotors
(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 ...
Dynamics of quasi-two-dimensional turbulent jets
(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 ...
Differential systems, moving frames, structure-preserving submersions and geometrical problems in physics
(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 ...
Aspects of higher dimensional Einstein theory and M-theory
(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 ...
Stability of fluid-loaded structures
(University of CambridgeSt John's College, 2011-06-07)
It is known theoretically that infinitely long fluid loaded plates in mean flow exhibit a range of unusual phenomena in the 'long time' limit. These include convective
instability, absolute instability and negative energy ...
Anti-self-dual fields and manifolds
(University of CambridgeDepartment of Applied Mathematics and Theoretical Physics, 2013-04-30)
In this thesis we study anti–self–duality equations in four and eight dimensions on manifolds of special Riemannian holonomy, among these hyper–Kähler,
Quaternion–Kähler and Spin(7)–manifolds.
We first consider the ...
Freeze fracturing of elastic porous media
(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 ...
Quantum theory from the perspective of general probabilistic theories
(University of CambridgeDepartment of Applied Mathematics and Theoretical Physics, 2015-03-03)
This thesis explores various perspectives on quantum phenomena, and how our understanding of these phenomena is informed by the study of general probabilistic theories. Particular attention is given to quantum nonlocality, ...
