We report on a successful implementation of a three-dimensional wavelet-based solver for the Poisson equation with Dirichlet boundary conditions, optimized for use in particle-in-cell (PIC) simulations. The solver is based on the operator formulation

Energy Trapping in Loaded String Models with Long- and Short-Range Couplings

Autor: Ilya V. Pogorelov, Henry E. Kandrup

Publikováno v: Annals of the New York Academy of Sciences. 1045:68-78

This note illustrates the possibility in simple loaded string models of trapping most of the system energy in a single degree of freedom for very long times, demonstrating in particular that the robustness of the trapping is enhanced by increasing th

Anisotropic distribution functions for relativistic galactic nuclei

Publikováno v: Physical Review E. 53:1375-1381

An integral transform is derived which, for a system of stars characterized as a spherical equilibrium solution to the collisionless Boltzmann equation of general relativity, allows the reconstruction of a two-integral distribution function from mome

The dynamics of electrons in the presence of a positive ion is considered for conditions of weak electron-electron couping but strong electron-ion coupling. The equilibrium electron density and electric field time correlation functions are evaluated
