Identifying ballistic modes via Poincaré sections
André Farinha Bósio, Iberê Luiz Caldas, Ricardo Luiz Viana +1
Exploring chaotic systems via Poincaré sections has proven essential in dynamical systems, yet measuring their characteristics poses challenges to identify the various dynamical re…
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…
Benchmark: Tao's symplectic integration method
Matheus Lazarotto, Iberê Caldas, Yves Elskens
A benchmark test was conducted for a new symplectic integration method originally developed by Molei Tao. The method raises interest due to its explicit evolution equation, with ap…
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…
