Meson Spectroscopy from Lattice QCD
(SpringerFew-Body Systems, 2017-05-01)
Some recent progress in using lattice QCD to perform first-principles calculations of the spectra of mesons is discussed. In particular, I highlight some new results on resonances, near-threshold states and related scattering ...
Topics in Computing with Quantum Oracles and Higher-Dimensional Many-Body Systems
(University of CambridgeDepartment of Applied Mathematics and Theoretical PhysicsTrinity College, 2017-06-08)
Since they were first envisioned, quantum computers have oft been portrayed as devices of limitless power, able to perform calculations in a mere instant that would take current computers years to determine. This is, of ...
Nonlinear evolution of linear optimal perturbations of strongly stratified shear layers
(Cambridge University PressJournal of Fluid Mechanics, 2017-08-25)
The Miles-Howard theorem states that a necessary condition for normal-mode instability in parallel, inviscid, steady stratified shear flows is that the minimum gradient Richardson number, $Ri_{g,min}$, is less than 1/4 ...
Mesoscale and Submesoscale Effects on Mixed Layer Depth in the Southern Ocean
(American Meteorological SocietyJournal of Physical Oceanography, 2017-09-01)
Submesoscale dynamics play a key role in setting the stratification of the ocean surface mixed layer and mediating air–sea exchange, making them especially relevant to anthropogenic carbon uptake and primary productivity ...
Bubble-based acoustic micropropulsors: active surfaces and mixers.
(Royal Society of ChemistryLab on a chip, 2017-04-04)
Acoustic micropropulsors present great potential for microfluidic applications. The propulsion is based on encapsulated 20 μm bubbles excited by a contacless ultrasonic transducer. The vibrating bubbles then generate a ...
The relaxation time for viscous and porous gravity currents following a change in flux
(Cambridge University PressJournal of Fluid Mechanics, 2017-06-01)
The equilibration time in response to a change in flux from Q to $\Lambda$Q after an injection period applied to either a low-Reynolds-number gravity current or one propagating through a porous medium, in both axisymmetric ...
Nonlinear spectral image fusion
(Lecture Notes in Computer Science (including subseries Lecture Notes in Artificial Intelligence and Lecture Notes in Bioinformatics), 2017-01-01)
© Springer International Publishing AG 2017. In this paper we demonstrate that the framework of nonlinear spectral decompositions based on total variation (TV) regularization is very well suited for image fusion as well ...
The inclusion of two-loop SUSYQCD corrections to gluino and squark pole masses in the minimal and next-to-minimal supersymmetric standard model: SOFTSUSY3.7
(ElsevierComputer Physics Communications, 2017-10)
We describe an extension of the SOFTSUSY spectrum calculator to include two-loop supersymmetric QCD (SUSYQCD) corrections of order O(α s 2 ) to gluino and squark pole masses, either in the minimal supersymmetric standard ...
Turbulent jets with off-source heating
(Cambridge University PressJournal of Fluid Mechanics, 2017-08-10)
Motivated by anomalous entrainment behaviour in cumulus clouds, Bhat et al. (Exp. Fluids, vol. 7, 1989, pp. 99–102) pioneered a laboratory experiment to study turbulent jets subjected to a volumetric heating away from the ...
Local models of astrophysical discs
(Oxford University PressMonthly Notices of the Royal Astronomical Society, 2017-12-01)
Local models of gaseous accretion discs have been successfully employed for decades to describe an assortment of small-scale phenomena, from instabilities and turbulence, to dust dynamics and planet formation. For the most ...
