Magnetoplasmons no sistema de elétrons superficiais sobre hélio líquido confinado em um canal parabólico
(Universidade Federal de São Carlos, 2003-04-15)
A lot of experimental and theoretical work have been performed in order to understand the collective modes of two-dimensional electron system (2DES) confined to restricted geometries. In particular, the system of surface ...
Efeitos de interações elétron-elétron e spin-órbita nas propriedades magneto-eletrônicas de magneto-transporte de sistemas confinados.
(Universidade Federal de São Carlos, 2003-10-10)
Effects of the direct and exchange electron-electron interaction, external magnetic
field, symmetry of the charge carriers confining potential, radius, material g-factor, and
also of the spin-orbit interaction in zincblende ...
Estudos sobre a inclusão da correlação eletrônica do alvo no espalhamento elástico elétron-molécula e sobre a ionização molecular por impacto de elétrons
(Universidade Federal de São Carlos, 2003-12-10)
In this work we present two contributions to the electron-molecule collision theory. Firstly, we present a new theoretical procedure to introduce the target electronic correlation in the elastic electron-molecule scattering. ...
Problema relativístico de dois corpos.
(Universidade Federal de São Carlos, 2003-12-08)
We study the relativistic two-body problem of the action-at-a-distance electrodynamics.
This dynamical system appeared 100 years ago as a time-symmetric relativistic
motion and acquired the status of electrodynamics in the ...
