Lorentz-symmetry Violation and Electrically Charged Vortices in the Planar Regime
H. Belich, T. Costa-Soares, M. M. Ferreira +2
We start from a Lorentz non-invariant Abelian-Higgs model in 1+3 dimensions, and carry out its dimensional reduction to . The planar model resulting thereof is composed by a…

Does the Higgs mechanism favour electron-electron bound states in Maxwell-Chern-Simons QED_3?
H. Belich, O. M. Del Cima, M. M. Ferreira +1
The low-energy electron-electron scattering potential is derived and discussed for the Maxwell-Chern-Simons model coupled to QED_3 with spontaneous symmetry breaking. One shows tha…

Surfaces of Constant negative Scalar Curvature and the Correpondence between the Liouvulle and the sine-Gordon Equations
H. Belich, G. Cuba, R. Paunov
By studying the {\it internal} Riemannian geometry of the surfaces of constant negative scalar curvature, we obtain a natural map between the Liouville, and the sine-Gordon equatio…
