Optimal 5-step nilpotent quadratic algebras

Natalia Iyudu, Stanislav Shkarin

By the Golod--Shafarevich Theorem, an associative algebra R given by n generators and d<n^2/3 homogeneous quadratic relations is not 5-step nilpotent. We prove that this estimate i…

Efficient photonic reformatting of celestial light for diffraction-limited spectroscopy

David G. MacLachlan, Robert J. Harris, Itandehui Gris-Sánchez +9

The spectral resolution of a dispersive astronomical spectrograph is limited by the trade-off between throughput and the width of the entrance slit. Photonic guided-wave transition…

Effective Field Theory and Electroweak Baryogenesis in the Singlet-Extended Standard Model

P. H. Damgaard, A. Haarr, D. O'Connell +1

Electroweak baryogenesis is a simple and attractive candidate mechanism for generating the observed baryon asymmetry in the Universe. Its viability is sometimes investigated in ter…

Evidence of Fanning in the Ophiuchus Stream

B. Sesar, A. M. Price-Whelan, J. G. Cohen +11

The Ophiuchus stellar stream presents a dynamical puzzle: its old stellar populations ( Gyr) cannot be reconciled with (1) its orbit in a simple model for the Milky Way po…

Gain and loss enhancement in active and passive particulate composite materials

Tom G. Mackay, Akhlesh Lakhtakia

Two active dielectric materials may be blended together to realize a homogenized composite material (HCM) which exhibits more gain than either component material. Likewise, two dis…

Maximizing diversity in biology and beyond

Tom Leinster, Mark W. Meckes

Entropy, under a variety of names, has long been used as a measure of diversity in ecology, as well as in genetics, economics and other fields. There is a spectrum of viewpoints on…

Determining the scale in Lattice QCD

V. G. Bornyakov, R. Horsley, R. Hudspith +8

We discuss scale setting in the context of 2+1 dynamical fermion simulations where we approach the physical point in the quark mass plane keeping the average quark mass constant. W…

A new gauge-invariant method for diagnosing eddy diffusivities

Julian Mak, James R. Maddison, David P. Marshall

Coarse resolution numerical ocean models must typically include a parameterisation for mesoscale turbulence. A common recipe for such parameterisations is to invoke down-gradient m…
