The resonant π+γ → π+π⁰ amplitude from Quantum Chromodynamics
(APSPhysical Review Letters, 2015-12-08)
We present the first ab initio calculation of a radiative transition of a hadronic resonance within Quantum Chromodynamics (QCD). We compute the amplitude for ππ → πγ* , as a function of the energy of the ππ pair and the ...
The Quantum Hall Effect in Supersymmetric Chern-Simons Theories
(APSPhysical Review B, 2015-12-15)
We introduce a supersymmetric Chern-Simons theory whose low energy physics is that of the fractional quantum Hall effect. The supersymmetry allows us to solve the theory analytically. We quantise the vortices and, by ...

A regularised singularity approach to phoretic problems
(SpringerThe European Physical Journal E, 2015-12-28)
An efficient, accurate, and flexible numerical method is proposed for the solution of the swimming problem of one or more autophoretic particles in the purely diffusive limit. The method relies on successive boundary element ...
Precessional instability in binary black holes with aligned spins
(American Physical SocietyPhysical Review Letters, 2015-10-02)
Binary black holes on quasicircular orbits with spins aligned with their orbital angular momentum
have been testbeds for analytic and numerical relativity for decades, not least because symmetry
ensures that such configurations ...
Worldsheet methods for perturbative quantum field theory
(University of CambridgeDepartment of Applied Mathematics and Theoretical PhysicsTrinity College, 2015-10-01)
This thesis is divided into two parts. The first part concerns the study of the ambitwistor string and the scattering equations, while the second concerns the interplay of the symmetries of the asymptotic null boundary of ...
A two-zone model for natural cross-ventilation
(ElsevierBuilding and Environment, 2015-07-01)
Cross-ventilation flows (CV) are characterized by significant inflow momentum conservation as fluid flows across an enclosed rectangular volume as a confined jet. When the inflow area is smaller than the volume cross-sectional ...
Gravity current propagation up a valley
(Cambridge University PressJournal of Fluid Mechanics, 2015-01-10)
The advance of the front of a dense gravity current propagating in a rectangular channel and V-shaped valley both horizontally and up a low slope is examined through theory, full-depth lock-release laboratory experiments ...
Sea-ice thermodynamics and brine drainage
(Royal Society PublishingPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2015-07-13)
Significant changes in the state of the Arctic ice cover are occurring. As the summertime extent of sea ice diminishes, the Arctic is increasingly characterized by first-year rather than multi-year ice. It is during the ...
On the stability of gravity with Dirichlet walls
(IoPClassical and Quantum Gravity, 2015-11-06)
Dirichlet walls - time-like boundaries at a finite distance from the bulk on which the induced metric is held fixed - have been used to model AdS spacetimes with a finite cutoff. In the context of gauge/gravity duality, ...
