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…
