Entropic Comparison of Atomic-Resolution Electron Tomography of Crystals and Amorphous Materials
(American Physical SocietyPhysical Review Letters, 2017-10-20)
Electron tomography bears promise for widespread determination of the three-dimensional arrangement of atoms in solids. However, it remains unclear whether methods successful for crystals are optimal for amorphous solids. ...
Lines of constant physics in a five-dimensional gauge-higgs unification scenario
(Proceedings of ScienceProceedings of Sciencehttps://pos.sissa.it/cgi-bin/reader/contribution.cgi?id=256/215, 2016-07-24)
We report on the progress in the study of a five-dimensional SU(2) Gauge-Higgs Unification model. In this non-perturbative study, the Higgs mechanism is triggered by the spontaneous breaking of a global symmetry. In the ...
Charmed Meson Scattering from Lattice QCD
(Proceedings of ScienceProceedings from the 8th International Workshop On Charm Physics, 2016-11-17)
State-of-the-art lattice QCD calculations of scattering amplitudes in coupled-channel Dπ, Dη and DsK¯ scattering, as well elastic DK scattering are discussed. The methodology employed allows a determination of the relevant ...
Zonal flows in accretion discs and their role in gravito-turbulence
(University of CambridgeDepartment of Applied Mathematics and Theoretical Physics (DAMTP)St Edmund's, 2017-10-01)
This thesis focuses on the evolution of zonal flows in self-gravitating accretion discs and their resulting effect on disc stability; it also studies the process of disc gravito-turbulence, with particular emphasis given ...
Spontaneous oscillations of elastic filaments induced by molecular motors.
(The Royal SocietyJournal of the Royal Society, Interface, 2017-11)
It is known from the wave-like motion of microtubules in motility assays that the piconewton forces that motors produce can be sufficient to bend the filaments. In cellular phenomena such as cytosplasmic streaming, molecular ...
Newtonian Twistor Theory
(University of CambridgeDAMTPTrinity College, 2017-10-01)
In twistor theory the nonlinear graviton construction realises four-dimensional antiself-
dual Einstein manifolds as Kodaira moduli spaces of rational curves in threedimensional
complex manifolds. We establish a Newtonian ...
Aerodynamic noise from rigid trailing edges with finite porous extensions
(Cambridge University PressJournal of Fluid Mechanics, 2018-02-10)
This paper investigates the effects of finite flat porous extensions to semi-infinite impermeable flat plates in an attempt to control trailing-edge noise through bio-inspired adaptations. Specifically the problem of sound ...
The Complexity of Translationally Invariant Spin Chains with Low Local Dimension
(Annales Henri Poincaré, 2017-11)
We prove that estimating the ground state energy of a
translationally-invariant, nearest-neighbour Hamiltonian on a 1D spin chain is
QMAEXP-complete, even for systems of low local dimension (roughly 40). This is
an improvement ...
Symmetries and geometrical properties of dynamical fluctuations in molecular dynamics
(Entropy, 2017-10-01)
We describe some general results that constrain the dynamical fluctuations that can occur in non-equilibrium steady states, with a focus on molecular dynamics. That is, we consider Hamiltonian systems, coupled to external ...
Alternating Direction Implicit (ADI) schemes for a PDE-based image osmosis model
(Journal of Physics: Conference Series, 2017-10-22)
© Published under licence by IOP Publishing Ltd. We consider Alternating Direction Implicit (ADI) splitting schemes to compute efficiently the numerical solution of the PDE osmosis model considered by Weickert et al. in ...
