Nonequilibrium Statistical Mechanics of Systems with Long-Range Interactions: Ubiquity of Core-Halo Distributions
Yan Levin, Renato Pakter, Felipe B. Rizzato +2
Systems with long-range (LR) forces, for which the interaction potential decays with the interparticle distance with an exponent smaller than the dimensionality of the embedding sp…
Controlling chaos in wave-particle interactions
M. C. de Sousa, I. L. Caldas, F. B. Rizzato +2
We analyze the behavior of a relativistic particle moving under the influence of a uniform magnetic field and a stationary electrostatic wave. We work with a set of pulsed waves th…
Standard map in magnetized relativistic systems: fixed points and regular acceleration
M. C. de Sousa, F. M. Steffens, R. Pakter +1
We investigate the concept of a standard map for the interaction of relativistic particles and electrostatic waves of arbitrary amplitudes, under the action of external magnetic fi…
Statistical Mechanics of Unbound Two Dimensional Self-Gravitating Systems
Tarcísio N. Teles, Yan Levin, Renato Pakter +1
We study, using both theory and molecular dynamics simulations, the relaxation dynamics of a microcanonical two dimensional self-gravitating system. After a sufficiently large time…
Thermodynamics of driven collisionless systems
Felipe B. Rizzato, Renato Pakter, Yan Levin
A statistical theory is presented which allows to calculate the stationary state achieved by a driven system after a process of collisionless relaxation. The theory is applied to s…
Collisionless relaxation in gravitational systems: From violent relaxation to gravothermal collapse
Yan Levin, Renato Pakter, Felipe B. Rizzato
Theory and simulations are used to study collisionless relaxation of a gravitational -body system. It is shown that when the initial one particle distribution function satisfies…
