Isoscalar ππ Scattering and the σ Meson Resonance from QCD
(American Physical SocietyPhysical Review Letters, 2017-01-13)We present for the first time a determination of the energy dependence of the isoscalar ππ elastic scattering phase shift within a first-principles numerical lattice approach to QCD. Hadronic correlation functions are ...

Kinetic effects regularize the mass-flux singularity at the contact line of a thin evaporating drop
We consider the transport of vapour caused by the evaporation of a thin, axisymmetric, partially wetting drop into an inert gas. We take kinetic effects into account through a linear constitutive law that states that the ...

Parameterization of Frontal Symmetric Instabilities. I: Theory for Resolved Fronts
(ElsevierOcean Modelling, 2017-01-01)A parameterization is proposed for the effects of symmetric instability (SI) on a resolved front. The parameterization is dependent on external forcing by surface buoyancy loss and/or down-front winds, which reduce potential ...

Zonal flow evolution and overstability in accretion discs
(Oxford University PressMonthly Notices of the Royal Astronomical Society, 2017-04-01)This work presents a linear analytical calculation on the stability and evolution of a compressible, viscous self-gravitating (SG) Keplerian disc with both horizontal thermal diffusion and a constant cooling time-scale ...

Extraction of gravitational-wave energy in higher dimensional numerical relativity using the Weyl tensor
© 2017 IOP Publishing Ltd. Gravitational waves are one of the most important diagnostic tools in the analysis of strong-gravity dynamics and have been turned into an observational channel with LIGO's detection of GW150914. ...

Meson spectroscopy, resonances and scattering on the lattice
I discuss some recent progress in studying the spectra of mesons using first-principles lattice QCD calculations. In particular, I highlight some new results on resonances, near-threshold states and related scattering ...

The Planar Ising Model and Total Positivity
(SpringerJournal of Statistical Physics, 2017-01-01)A matrix is called totally positive (resp. totally nonnegative) if all its minors are positive (resp. nonnegative). Consider the Ising model with free boundary conditions and no external field on a planar graph G. Let ...

Excited and exotic charmonium, $\textit{D}$$_{s}$ and $\textit{D}$ meson spectra for two light quark masses from lattice QCD
(SpringerJournal of High Energy Physics, 2016-12-19)We present highly-excited charmonium, $\textit{D}$$_{s}$ and $\textit{D}$ meson spectra from dynamical lattice QCD calculations with light quarks corresponding to $\textit{M}$$_{π}$ ∼ 240 MeV and compare these to previous ...

Non-abelian 3$D$ bosonization and quantum Hall states
(SpringerJournal of High Energy Physics, 2016-12-01)Bosonization dualities relate two different Chern-Simons-matter theories, with bosonic matter on one side replaced by fermionic matter on the other. We first describe a more general class of non-Abelian bosonization ...

Can phoretic particles swim in two dimensions?
(American Physical SocietyPhysical Review E, 2016-12-16)Artificial phoretic particles swim using self-generated gradients in chemical species (self-diffusiophoresis) or charges and currents (self-electrophoresis). These particles can be used to study the physics of collective ...

Derivative of the standard $p$-adic $L$-function associated with a Siegel form
In this paper we construct a two variables p-adic L-function for the standard representation associated with a Hida family of parallel weight genus g Siegel forms, using a method previously developed by B\"ocherer--Schmidt ...

Shadows of Teichmüller Discs in the Curve Graph
We consider several natural sets of curves associated to a given Teichmüller disc, such as the systole set or cylinder set, and study their coarse geometry inside the curve graph. We prove that these sets are quasiconvex ...

Helical propulsion in shear-thinning fluids
(Cambridge University PressJournal of Fluid Mechanics, 2017-02-01)Swimming micro-organisms often have to propel themselves in complex non-Newtonian fluids. We carry out experiments with self-propelling helical swimmers driven by an externally rotating magnetic field in shear-thinning ...

An upper bound for the pseudoisotopy stable range
(SpringerMathematische Annalen, 2017-08-01)We prove that the pseudoisotopy stable range for manifolds of dimension 2n can be no better than (2n - 2). In order to do so, we define new characteristic classes for block bundles, extending our earlier work with Ebert, ...

Long-range interactions, wobbles, and phase defects in chains of model cilia
(American Physical SoceityPhysical Review Fluids, 2016-12-13)Eukaryotic cilia and flagella are chemo-mechanical oscillators capable of generating long-range coordinated motions known as metachronal waves. Pair synchronization is a fundamental requirement for these collective dynamics, ...

Microscale flow dynamics of ribbons and sheets
(Royal Society of ChemistrySoft Matter, 2017-01-18)Numerical study of the hydrodynamics of thin sheets and ribbons presents difficulties associated with resolving multiple length scales. To circumvent these difficulties, asymptotic methods have been developed to describe ...

Teichmüller spaces and bounded symmetric domains do not mix isometrically
(SpringerGeometric and Functional Analysis, 2017-06-01)This paper shows that, in dimensions two or more, there are no holomorphic isometries between Teichüller spaces and bounded symmetric domains in their intrinsic Kobayashi metric.

Detrainment of plumes from vertically distributed sources
(SpringerEnvironmental Fluid Mechanics, 2016-11-22)We present experimental results demonstrating that, for the turbulent plume from a buoyancy source that is vertically distributed over the full area of a wall, detrainment qualitatively changes the shape of the ambient ...
