On the momentum space structure of the quark propagator
O. Oliveira, T. Frederico, W. de Paula
The structure of the quark propagator in momentum space is explored taking into account non-perturbative QCD dynamics constraints for the quark spectral densities derived previousl…
On the conformal limit of a QED-inspired model
O Oliveira, T Frederico, W de Paula
A conformal invariant QED-inspired model is solved for a general covariant linear gauge using the Dyson-Schwinger equations for the propagators assuming a pure vector like interact…
Optical conductivity of curved graphene
A. J. Chaves, T. Frederico, O. Oliveira +2
We compute the optical conductivity for an out-of-plane deformation in graphene using an approach based on solutions of the Dirac equation in curved space. Different examples of pe…
Dark/Visible Parallel Universes and Big Bang Nucleosynthesis
C. A. Bertulani, T. Frederico, J. Fuqua +3
We develop a model for visible matter-dark matter interaction based on the exchange of a massive gray boson called herein the Mulato. Our model hinges on the assumption that all kn…
Charge confinement and Klein tunneling from doping graphene
C. Popovici, O. Oliveira, W. de Paula +1
In the present work, we investigate how structural defects in graphene can change its transport properties. In particular, we show that breaking of the sublattice symmetry in a gra…
A Democratic Gauge Model for Dark/Visible Matter Symmetry
O. Oliveira, C. A. Bertulani, M. S. Hussein +2
We develop a model for visible matter-dark matter interaction based on the exchange of a weakly interacting massive gauge boson called herein the WIMG. Our model hinges on the assu…
