Effective transport barriers in the biquadratic nontwist map
Gabriel C. Grime, Ricardo L. Viana, Yves Elskens Iberê L. Caldas
Nontwist area-preserving maps violate the twist condition at specific orbits, resulting in shearless invariant curves that prevent chaotic transport. Plasmas and fluids with nonmon…
Larmor radius effect on the control of chaotic transport in tokamaks
L. A. Osorio-Quiroga, M. Roberto, R. L. Viana +2
We investigate the influence of the finite Larmor radius on the dynamics of guiding-center test particles subjected to an drift in a large aspect-rat…
Shearless effective barriers to chaotic transport induced by even twin islands in nontwist systems
M. Mugnaine, J. D. Szezech, R. L. Viana +2
For several decades now it has been known that systems with shearless invariant tori, nontwist Hamiltonian systems, possess barriers to chaotic transport. These barriers are resili…
