Semiclassical instabilities of Kerr-anti-de Sitter black holes
(Physical Review D - Particles, Fields, Gravitation and Cosmology, 2010-01-05)
On three-point correlation functions in the gauge/gravity duality
(Journal of High Energy Physics, 2010-12-09)
The instanton liquid and the axion
(University of CambridgeDepartment of Applied Mathematics and Theoretical Physics, 2010-05-04)
The ultimate goal of this thesis is to improve our understanding of the cosmology of axions. Axions couple to QCD
instantons and these non-perturbative effects are modeled within the framework of the interacting instanton ...
Numerical solutions of the general relativistic equations for black hole fluid dynamics
(University of CambridgeDepartment of Applied Mathematics and Theoretical PhysicsSelwyn College, 2010-05-04)
The aims of this thesis are to develop and validate a robust and efficient algorithm for the numerical solution of the equations of General Relativistic Hydrodynamics, to implement the algorithm in a computationally efficient ...
Heavy quark physics on the lattice with improved nonrelativistic actions
(University of CambridgeDepartment of Applied Mathematics and Theoretical PhysicsSt John's College, 2010-03-16)
Hadrons containing heavy quarks, in particular b quarks, play an important role in high energy physics. Measurements of their electroweak interactions are
used to test the Standard Model and search for new physics. For ...
Numerical methods for systems of highly oscillatory ordinary differential equations
(University of CambridgeDepartment of Applied Mathematics and Theoretical Physics, 2010-06-08)
This thesis presents methods for efficient numerical approximation of linear and non-linear systems of highly oscillatory ordinary differential equations.
Phenomena of high oscillation is considered a major computational ...
Variability of black-hole accretion discs: a theoretical study
(University of CambridgeDepartment of Applied Mathematics and Theoretical PhysicsTrinity College, 2010-06-08)
Accretion discs are fluid-dynamical entities which surround many black holes. Observations
reveal that these systems exhibit variability on a range of time scales. This thesis investigates phenomena occurring in black-hole ...
Rayleigh-Taylor mixing: confinement by stratification and geometry
(University of CambridgeDepartment of Applied Mathematics and Theoretical PhysicsSelwyn College, 2010-03-16)
Rayleigh-Taylor instability has been an area of active research in fluid dynamics for
the last twenty years, but relatively little attention has been paid to the dynamics
of problems where Rayleigh-Taylor instability ...
Initial and boundary value problems in two and three dimensions
(University of CambridgeDepartment of Applied Mathematics and Theoretical PhysicsTrinity College, 2010-04-13)
This thesis: (a) presents the solution of several boundary value problems (BVPs) for the Laplace and the modified Helmholtz
equations in the interior of an equilateral triangle; (b) presents the solution of the heat ...
The effects of stochastic forces on the evolution of planetary systems and Saturn's rings
(University of CambridgeDepartment of Applied Mathematics and Theoretical Physics, 2010-10-12)
The increasing number of discovered extra-solar planets opens a new opportunity for studies of the formation of planetary systems. Their diversity keeps challenging the long-standing theories which were based on data ...
