Symmetric multistep methods for charged - particle dynamics
A class of explicit symmetric multistep methods is proposed for integrating the equations of motion of charged particles in an electro-magnetic field. The magnetic forces are built into these methods in a special way that respects the Lagrangian structure of the problem. It is shown that such methods approximately preserve energy and momentum over very long times, proportional to a high power o...
متن کاملMolecular dynamics simulations of polyelectrolyte multilayering on a charged particle.
Molecular dynamics simulations of polyelectrolyte multilayering on a charged spherical particle revealed that the sequential adsorption of oppositely charged flexible polyelectrolytes proceeds with surface charge reversal and highlighted electrostatic interactions as the major driving force of layer deposition. Far from being completely immobilized, multilayers feature a constant surge of chain...

متن کاملChaotic dynamics and halo formation in charged-particle beams
An old problem, but a new area of fundamental research, is characterizing orbital dynamics and its consequences in time-dependent potentials. Regarding nonequilibrium space-charge potentials, one clear consequence is halo formation. We show that orbital chaos normally plays a central role in halo formation. In turn, the ability to quantify chaos is centrally important. We show examples of the g...
متن کاملClassical Langevin dynamics of a charged particle moving on a sphere and diamagnetism: A surprise
It is generally known that the orbital diamagnetism of a classical system of charged particles in thermal equilibrium is identically zero – the Bohr-van Leeuwen theorem. Physically, this null result derives from the exact cancellation of the orbital diamagnetic moment associated with the complete cyclotron orbits of the charged particles by the paramagnetic moment subtended by the incomplete or...
