Escape and transport in chaotic motion of charged particles in a magnetized plasma under the influence of two and three modes of drift waves
P. Haerter, E. D. Leonel, R. L. Viana
This study investigates how two- and three-wave configurations govern particle escape and transport in tokamak edge plasmas. Using a Hamiltonian model derived from drift-wave turbu…
Basin entropy and the impact of the escape positioning in an open area-preserving map
P. Haerter, R. L. Viana, M. A. F. Sanjuán
The main properties of a dynamical system can be analyzed by examining the corresponding basins, either attraction basins in dissipative systems or escape basins in open Hamiltonia…
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…
Ratchet current and scaling properties in a nontwist mapping
Matheus Rolim Sales, Daniel Borin, Leonardo Costa de Souza +4
We investigate the transport of particles in the chaotic component of phase space for a two-dimensional, area-preserving nontwist map. The survival probability for particles within…
Riddling: Chimera's dilemma
Vagner dos Santos, José Danilo Szezech Júnior, Antonio Marcos Batista +8
We investigate the basin of attraction properties and its boundaries for chimera states in a circulant network of Hénon maps. Chimera states, for which coherent and incoherent doma…
