Optimal velocity fields for instantaneous magnetic field growth
Nicholas J. Moore, Stefan G. Llewellyn Smith
We consider a variant of the kinematic dynamo problem. Rather than prescribing a velocity field and searching for high-growth magnetic fields via an eigenvalue problem, we treat th…

Low-order reaction-diffusion system approximates heat transfer and flow structure in annular convection
Yuejia Zhang, Nicholas J. Moore, Jinzi Mac Huang
Heat transfer in a fluid can be greatly enhanced by natural convection, giving rise to the nuanced relationship between the Nusselt number and Rayleigh number that has been a focus…

In search of rogue waves: a novel proposal distribution for parallelized rejection sampling of the truncated KdV Gibbs measure
Nicholas J. Moore, Brendan Foerster
The Gibbs ensemble of the truncated KdV (TKdV) equation has been shown to accurately describe the anomalous wave statistics observed in laboratory experiments, in particular the em…
