Vortices and the saturation of the vertical shear instability in protoplanetary discs
(Monthly Notices of the Royal Astronomical Society, 2018-03-01)
Analytic and Numerical aspects of isospectral flows
(University of CambridgeDepartment of Applied Mathematics and Theoretical Physics (DAMTP)Wolfson College, 2018-01-15)
In this thesis we address the analytic and numerical aspects of isospectral flows. Such flows occur in mathematical physics and numerical linear algebra. Their main structural feature is to retain the eigenvalues in the ...
Lattice QCD calculation of the B-(s) -> D-(s)* lv form factors at zero recoil and implications for vertical bar V-cb vertical bar
(PHYSICAL REVIEW D, 2018-03-09)
© 2018 authors. We present results of a lattice QCD calculation of B→D∗ and Bs→Ds∗ axial vector matrix elements with both states at rest. These zero recoil matrix elements provide the normalization necessary to infer a ...
Large-scale stability and astronomical constraints for coupled dark-energy models
(American Physical SocietyPhysical Review D, 2018-02-26)
The physics of the dark energy and the dark matter is still an open issue in cosmology. The dark energy occupies about 68.5% of the total energy density of the universe today , and is believed to accelerate its observed ...
Rough surface reconstruction at grazing angles by an iterated marching method.
(Optical Society of AmericaJournal of the Optical Society of America. A, Optics, image science, and vision, 2018-04)
An iterated marching method is presented for reconstruction of rough perfectly reflecting 1-dimensional surfaces from scattered data arising from a scalar wave at grazing incidence. This is based on coupled inte- gral ...
A possible failure of determinism in general relativity
(American Physical SocietyPhysics, 2018-01-17)
Is the future predictable? If we know the initial state of a system exactly, then do the laws of physics determine its state arbitrarily far into the future? In Newtonian mechanics, the answer is yes. Similarly in ...
Exploring cosmic origins with CORE: Gravitational lensing of the CMB
(Journal of Cosmology and Astroparticle Physics, 2018-04-05)
High accuracy computational methods for the semiclassical Schrödinger equation
(University of CambridgeDepartment of Applied Mathematics and Theoretical Physics (DAMTP)King's College, 2018-04-28)
The computation of Schrödinger equations in the semiclassical regime presents several enduring challenges due to the presence of the small semiclassical parameter. Standard approaches for solving these equations commence ...
The structure and origin of confined Holmboe waves
(Cambridge University PressJournal of Fluid Mechanics, 2018-08-10)
Finite-amplitude manifestations of stratified shear flow instabilities and their spatio-temporal coherent structures are believed to play an important role in turbulent geophysical flows. Such shear flows commonly have ...
