Energy and momentum conservation in the Euler-Poincaré formulation of local Vlasov-Maxwell-type systems
Eero Hirvijoki, Joshua W. Burby, David Pfefferlé +1
The action principle by Low [Proc. R. Soc. Lond. A 248, 282--287] for the classic Vlasov-Maxwell system contains a mix of Eulerian and Lagrangian variables. This renders the Noethe…
Rigidity of MHD equilibria to smooth incompressible ideal motion near resonant surfaces
David Pfefferlé, Lyle Noakes, Yao Zhou
In ideal MHD, the magnetic flux is advected by the plasma motion, freezing flux-surfaces into the flow. An MHD equilibrium is reached when the flow relaxes and force balance is ach…
WWhittle Maximum Likelihood Estimate of spectral properties of Rayleigh-Taylor interfacial mixing using hot-wire anemometry experimental data
David Pfefferlé, Snezhana I Abarzhi
Investigating the power density spectrum of fluctuations in Rayleigh-Taylor (RT) interfacial mixing is a means of studying characteristic length- and time-scales, anisotropies and…
Equivalent elastica knots
Alain J. Brizard, David Pfefferlé
The problem of an elastica knot in three-dimensional space is solved explicitly by expressing the Frenet-Serret curvature and torsion of the knot in terms of the Weierstrass and Ja…
