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 ...

Classical and quantum solutions in Brans-Dicke cosmology with a perfect fluid
(American Physical SocietyPhysical Review D, 2016)
We consider the application of group invariant transformations in order to constrain a flat isotropic and homogeneous cosmological model, containing of a Brans-Dicke scalar field and a perfect fluid with a constant equation ...
Distinguishing black-hole spin-orbit resonances by their gravitational wave signatures. II: Full parameter estimation
(American Physical Society, 2016)
Gravitational waves from coalescing binary black holes encode the evolution of their spins prior to merger. In the post-Newtonian regime and on the precession timescale, this evolution has one of three morphologies, with ...
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 ...
Slender-ribbon theory
(American Institute of PhysicsPhysics of Fluids, 2016-01-11)
Ribbons are long narrow strips possessing three distinct material length scales (thickness, width, and length) which allow them to produce unique shapes unobtainable by wires or filaments. For example, when a ribbon has ...
Evaporation effects in elastocapillary aggregation
(Cambridge University PressJournal of Fluid Mechanics, 2016)
We consider the effect of evaporation on the aggregation of a number of elastic objects due to a liquid’s surface tension. In particular, we consider an array of spring–block elements in which the gaps between blocks are ...
End point of Black Ring Instabilities and the Weak Cosmic Censorship Conjecture
(American Physical SocietyPhysical Review Letters, 2016-02-18)
We produce the first concrete evidence that violation of the weak cosmic censorship conjecture can occur in asymptotically flat spaces of five dimensions by numerically evolving perturbed black rings. For certain thin ...
