One-loop calculations in Lorentz-breaking theories and proper-time method
A. F. Ferrari, J. Furtado, J. F. Assunção +2
We discuss applications of the proper-time method in various minimal Lorentz violating modifications of QED and present new results obtained with its use. Explicitly. we calculate…
Pseudo-Hermitian Dirac operator on the torus for massless fermions under the action of external fields
Ö. Yeşiltaş, J. Furtado
The Dirac equation in dimensions on the toroidal surface is studied for a massless fermion particle under the action of external fields. Using the covariant approach based…
Dirac equation on a catenoid bridge: a supersymmetric approach
Ö. Yeşiltaş, J. Furtado, J. E. G. Silva
In this paper, we study the Dirac equation for an electron constrained to move on a catenoid surface. We decoupled the two components of the spinor and obtained two Klein-Gordon-li…
Relativistic Bose-Einstein condensate in the rainbow gravity
J. Furtado, J. F. Assunção, C. R. Muniz
In this paper, we study the effects of a modified theory of gravity - the rainbow gravity - on the relativistic Bose-Einstein condensate (BEC). We initially discuss some formal asp…
Position-dependent mass effects on a bilayer graphene catenoid bridge
J. E. G. Silva, J. Furtado, A. C. A. Ramos
We study the electronic properties of a position-dependent effective mass electron on a bilayer graphene catenoid bridge. We propose a position-dependent mass (PDM) as a function o…
Bose-Einstein condensation in Hořava-Lifshitz theory
J. Furtado, J. F. Assunção, A. C. A. Ramos
In this paper we study the corrections emergent from a Hořava-Lifshitz extension of the complex scalar sector to the Bose-Einstein condensation and to the thermodynamics parameters…
