Eletrodinâmica de ordem superior em (2+1)D
(2007-06-15) [Tese de doutorado]
We present in this work a number of results in Poldolsky's formulation of the (2+1) dimensional Electromagnetism. We focus our attention on the nonrelativistic regime of scatterings. We analyse the possibility of existence ...
Pseudomecânica: partículas de spins inteiros, semi-inteiros e fracionários
(2007-02-28) [Tese de doutorado]
We use the pseudomechanics to study non relativistic particles and massive and massless relativistic particles, all of them with spin. In this last case massless, we have two situations: in the first one, we built an ...
Construção exata de sólitons de Hopf
(2007-07-27) [Tese de doutorado]
ur object of study are classical field theories which possesses topological solitons and have a infnite number of conserved quantities .In particular our models have what is know as Hopf charge. This charge appears because, ...
Dinâmica de campos escalares fora do equilíbrio
(2007-06-28) [Tese de doutorado]
We consider the nonequilibrium dynamics of the formation of a condensate in a spontaneously broken'lâmbda fi' POT. 4' relativistic quantum scalar field theory. The equation of motion of the corresponding order parameter ...
