Critical Exponent for the Lyapunov Exponent and Phase Transitions -- The Generalized Hamiltonian Mean-Field Model
Moisés F. P. Silva, Tarcísio M. Rocha Filho, Yves Elskens
We compute semi-analytic and numerical estimates for the largest Lyapunov exponent in a many-particle system with long-range interactions, extending previous results for the Hamilt…
Cross-field chaotic transport of electrons by ExB electron drift instability in Hall thruster
D. Mandal, Y. Elskens, N. Lemoine +1
A model calculation is presented to characterize the anomalous cross-field transport of electrons in a Hall thruster geometry. The anomalous nature of the transport is attributed t…
DIMOHA: A Time-Domain Algorithm for Traveling-Wave Tube Simulations
Damien Minenna, Yves Elskens, Frédéric André +3
To simulate traveling-wave tubes (TWTs) in time domain and more generally the wave-particle interaction in vacuum devices, we developed the DIscrete MOdel with HAmiltonian approach…
Hard-core collisional dynamics in the hamiltonian mean-field model
Luciano Miranda Filho, Igor Melo, Annibal Figueiredo +3
We consider a modification of the well studied Hamiltonian Mean-Field model by introducing a hard-core point-like repulsive interaction and propose a numerical integration scheme t…
Cross-field chaotic transport of electrons by electron drift instability in Hall thrusters
Debraj Mandal, Yves Elskens, Nicolas Lemoine +1
One special interest for the industrial development of Hall thruster is characterizing the anomalous cross-field electron transport observed after the channel exit. Since the ioniz…
Contribution of individual degrees of freedom to Lyapunov vectors in many-body systems
L Filho, M Amato, Y Elskens +1
We use the weight I, deduced from the estimation of Lyapunov vectors, in order to characterise regions in the kinetic (x, v) space with particles that most contribute to chaotic…
