Generalized Bogoliubov Transformation, Fermion Field and Casimir Effect in a Box
H. Queiroz, J. C. da Silva, F. C. Khanna +2
In this work a generalization of the Bogoliubov transformation is developed to describe a space compactified fermionic field. The method is the fermion counterpart of the formalism…

Spinorial density matrix equation and gauge covariance
F. C. Khanna, A. E. Santana, A. Matos Neto +2
In this work we apply the Lie group representation method introduced in the real time formalism for finite-temperature quantum-field theory, thermofield dynamics, to derive a spino…

Hopf Structure in Nambu-Lie n-Algebras
A. E. Santana, R. Muradian
We give a definition and study Hopf structures in ternary (and n-ary) Nambu-Lie algebra. The fundamental concepts of 3-coalgebra, 3-bialgebra and Hopf 3- algebra are introduced. So…
