O operador espalhamento para férmions num campo externo em Thermofield Dynamics
(Universidade Estadual Paulista (Unesp), 2002-08)
O método de segunda quantificação é utilizado para construir o operador espalhamento S no espaço de Fock, no contexto de Thermofield Dynamics (TFD), para o campo de Dirac sujeito a um potencial eletromagnético externo ...

On the Nonequilibrium Statistical Operator and Classical Thermofield Dynamics
(Brazilian Journal of Physics, 1997)
Bogoliubov transformation for quantum fields in (Bbb S1)d × Bbb RD−d topology and applications to the Casimir effect
(2009)
A Bogoliubov transformation accounting simultaneously for spatial compactifica-tion and thermal effects is introduced. The fields are described in a ΓDd = Bbb S11 × ... × Bbb S1d × Bbb RD−d topology, and the Bogoliubov ...
On the Nonequilibrium Statistical Operator and Classical Thermofield Dynamics
(Brazilian Journal of Physics, 1997)
A nonequilibrium statistical operator (NSO) is built for classical sistems using a field theory in
classical phase space, which is but a classical version of the thermofield dynamics formalism. The
approach developed here ...
Thermofield dynamics extension of the open string field theory
(American Physical Society, 2016-03)
We study the application of the rules of thermofield dynamics (TFD) to the covariant formulation of open-string field theory. We extend the states space and fields according to the duplication rules of TFD and construct ...
