Adiabatic-nonadiabatic transition in warm long-range interacting systems : the transport of intense inhomogeneous beams
(2012) [Artículo de periódico]We investigate the role of the temperature in the onset of singularities and the consequent breakdown in a macroscopic fluid model for long-range interacting systems. In particular, we consider an adiabatic fluid description ... -
Driven one-component plasmas
(2009) [Artículo de periódico]A statistical theory is presented that allows the calculation of the stationary state achieved by a driven one-component plasma after a process of collisionless relaxation. The stationary Vlasov equation with appropriate ... -
Plasma emission by weak turbulence processes
(2014) [Artículo de periódico]The plasma emission is the radiation mechanism responsible for solar type II and type III radio bursts. The first theory of plasma emission was put forth in the 1950s, but the rigorous demonstration of the process based ... -
Relaxation of intense inhomogeneous charged beams
(2009) [Artículo de periódico]This work analyzes the dynamics of inhomogeneous, magnetically focused high intensity beams of charged particles. Initial inhomogeneities lead to density waves propagating transversely in the beam core, and the presence ... -
Simulação do diodo de Pierce com feixe de elétrons térmico
(2014) [Tesinas de grado]Este trabalho trata da dinâmica do diodo de Pierce com um feixe de elétrons térmico. O uso do termo térmico está relacionado ao aumento da dispersão em velocidade, em relação à velocidade média, ou seja, a partir da ... -
Simulation of asymmetric solar wind electron distributions
(2009) [Artículo de periódico]The electron distributions detected in the solar wind feature varying degrees of anisotropic high-energy tail. In a recent work the present authors numerically solved the one-dimensional electrostatic weak turbulence ... -
The controlling role of envelope mismatches in intense inhomogeneous charged beams
(2010) [Artículo de periódico]Inhomogeneous cold beams undergo wave breaking as they move along the axis of a magnetic focusing system. All the remaining control parameters fixed, the earliest wave breaking is a sensitive function of the inhomogeneity ...
