Generalized Gauge Transformations and Regularized $λ ϕ^{4}$ -type Abelian Vertices

Winder A. Moura-Melo, J. A. Helayel-Neto

Abelian Lagrangians containing $λ ϕ^{4}$ -type vertices are regularized by means of a suitable point-splitting scheme combined with generalized gauge transformations. The calculation…

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…
