Resonant oscillations in -dynamos on a closed, twisted Riemannian 2D flux tubes
Garcia de Andrade
Chicone et al [CMP (1995)] have shown that, kinematic fast dynamos in diffusive media, could exist only on a closed, 2D Riemannian manifold of constant negative curvature. This rep…
Magnetic filamentary structures in the dynamo spectrum in plasmas
Garcia de Andrade
Kinney et al [PPL \textbf{1},(1994)] have investigated plasma filamentary structure dynamics. More recently, Wilkin et al [Phys Rev Lett \textbf{99}:134501,(2007)] have shown that…
Slow dynamo modes in compact Riemannian plasma devices from Brazilian spherical tokamak data
Garcia de Andrade
Anti-dynamo modes are usually found in spheromaks plasma devices experiments due to the fact that Cowling anti-dynamo theorem is naturally applied to axisymmetric devices and flows…
Plasma torus dynamos versus laminar plasma dynamos
Garcia de Andrade
Earlier Wang et al [Phys Plasmas (2002)] have estimated a growth rate for the magnetic field of and flow ionization velocity of in a laminar plasma slow dyna…
Geodesic plasma flows instabilities of Riemann twisted solar loops
Garcia de Andrade
Riemann and sectional curvatures of magnetic twisted flux tubes in Riemannian manifold are computed to investigate the stability of the plasma astrophysical tubes. The geodesic equ…
Plasma metric singularities in helical devices and tearing instabilities in tokamaks
Garcia de Andrade
Plasma toroidal metric singularities in helical devices and tokamaks, giving rise to magnetic surfaces inside the plasma devices are investigated in two cases. In the first we cons…
A Riemannian geometrical method to classify tearing instabilities in plasmas
Garcia de Andrade
Riemannian geometrical tools, such as Ricci collineations and Killing symmetries, so often used in Einstein general theory of gravitation are here applied to plasma physics to buil…
MHD dynamo generation via Riemannian soliton theory
L. C. Garcia de Andrade
Heisenberg spin equation equivalence to nonlinear Schrödinger equation recently demonstrated by Rogers and Schief, is applied to the investigation of vortex filaments in magnetohyd…
