Aether field coupled to the electromagnetic field in the TFD formalism
R. Corrêa, L. H. A. R. Ferreira, A. F. Santos +1
In this paper, the aether field, which leads to the violation of Lorentz symmetries, coupled with the electromagnetic field is considered. In order to study thermal and size effect…
A Quasi Self-Dual Skyrme Model
L. A. Ferreira, L. R. Livramento
It has been recently proposed a modification of the Skyrme model which admits an exact self-dual sector by the introduction of six scalar fields assembled in a symmetric, positive…
TFD formalism: applications to the scalar field in a Lorentz-violating theory
L. H. A. R. Ferreira, A. F. Santos, Faqir C. Khanna
The Thermofield Dynamics (TFD) formalism is considered. In this context, a Lorentz-breaking scalar field theory is introduced. In contrast to the Matsubara formalism, the best-know…
A Generalised Self-Duality for the Yang-Mills-Higgs System
L. A. Ferreira, H. Malavazzi
Self-duality is a very important concept in the study and applications of topological solitons in many areas of Physics. The rich mathematical structures underlying it lead, in man…
Self-Duality in the Context of the Skyrme Model
L. A. Ferreira, L. R. Livramento
We study a recently proposed modification of the Skyrme model that possesses an exact self-dual sector leading to an infinity of exact Skyrmion solutions with arbitrary topological…
Self-dual sectors for scalar field theories in (1 + 1) dimensions
L. A. Ferreira, P. Klimas, Wojtek J. Zakrzewski
We use ideas of generalized self-duality conditions to construct real scalar field theories in (1 + 1)-dimensions with exact self dual sectors. The approach is based on a pre-poten…
