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…
Electron-electron bound states in parity-preserving QED_3 applied to high-T_c cuprate superconductors
H. R. Christiansen, O. M. DelCima, M. M. Ferreira +1
We consider a parity-preserving QED_3 model with spontaneous breaking of the gauge symmetry as a framework for the evaluation of the electron-electron interaction potential underly…
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…
Low-energy electron-electron bound states in planar QED
H. R. Christiansen, O. M. Del Cima, M. M. Ferreira +1
In this talk, we present a parity-preserving QED3 model with spontaneous breaking of a local U(1)-symmetry. The breaking is accomplished by a potential of the phi^6-type. It is sho…
