Wavelet-based density estimation for noise reduction in plasma simulations using particles
Romain Nguyen van yen, Diego del-Castillo-Negrete, Kai Schneider +2
For given computational resources, the accuracy of plasma simulations using particles is mainly held back by the noise due to limited statistical sampling in the reconstruction of…
Truncation effects in superdiffusive front propagation with Lévy flights
Diego del-Castillo-Negrete
A numerical and analytical study of the role of exponentially truncated Lévy flights in the superdiffusive propagation of fronts in reaction-diffusion systems is presented. The stu…
Finite Larmor radius effects on non-diffusive tracer transport in a zonal flow
K. Gustafson, D. del-Castillo-Negrete, W. Dorland
Finite Larmor radius (FLR) effects on non-diffusive transport in a prototypical zonal flow with drift waves are studied in the context of a simplified chaotic transport model. The…
Fluctuation-driven directed transport in the presence of Levy flights
D. del-Castillo-Negrete, V. Yu. Gonchar, A. V. Chechkin
Numerical evidence of directed transport driven by symmetric Levy noise in time-independent ratchet potentials in the absence of an external tilting force is presented. The results…
Non-diffusive transport in plasma turbulence: a fractional diffusion approach
D. del-Castillo-Negrete, B. A. Carreras, V. E. Lynch
Numerical evidence of non-diffusive transport in three-dimensional, resistive pressure-gradient-driven plasma turbulence is presented. It is shown that the probability density func…
Diffusive transport and self-consistent dynamics in coupled maps
Guido Boffetta, Diego del-Castillo-Negrete, Cristobal Lopez +2
The study of diffusion in Hamiltonian systems has been a problem of interest for a number of years. In this paper we explore the influence of self-consistency on the diffusion prop…
