Effects of the Internal Transport Barrier in the plasma confinement with Resonant Magnetic Perturbations
P. Haerter, L. C. Souza, R. L. Viana +1
In the pursuit of steady-state fusion energy, Advanced Tokamak regimes rely on Internal Transport Barriers (ITBs) with reversed magnetic shear. While Resonant Magnetic Perturbation…
Bayesian Basin Tracking: Efficient Global Continuation of Multistable Dynamical Systems
Pedro Haerter, Alexandre Wagemakers, Alvar Daza +1
Mapping the global phase space of high-dimensional multistable dynamical systems is computationally prohibitive because conventional approaches require extensive numerical integrat…
From Hyperbolic to Non-Hyperbolic Open Billiards: An Entropy and Scaling Law Approach
P. Haerter, A. F. Bosio, E. D. Leonel +2
We investigate the escape dynamics in an open circular billiard under the influence of a uniform gravitational field. The system properties are investigated as a function of the pa…
The effect of parameter drift in the transport of magnetized plasma particles
P. Haerter, R. L. Viana
We investigate how time dependent modulations of drift wave amplitudes affect particle transport and chaos in a magnetized plasma. Using the Horton model, we apply a sawtooth ramp…
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…
Synchronization of phase oscillators due to nonlocal coupling mediated by the slow diffusion of a substance
Pedro Haerter, Ricardo L. Viana
Many systems of physical and biological interest are characterized by assemblies of phase oscillators whose interaction is mediated by a diffusing chemical. The coupling effect res…
