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…
Superconducting transition temperature in thin films
A. P. C. Malbouisson, J. M. C. Malbouisson, A. E. Santana
By considering the Ginzburg-Landau model, compactified in one of the spatial dimensions, and using a modified Matsubara formalism, we determine the dependence of the superconductin…
Decoherence of Quantum Damped Oscillators
Sang Pyo Kim, Ademir E. Santana, F. C. Khanna
Quantum dissipation is studied within two model oscillators, the Caldirola-Kanai (CK) oscillator as an open system with one degree of freedom and the Bateman-Feshbach-Tikochinsky (…
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…
