Electron-pair condensation in parity-preserving QED3
M. A. De Andrade, O. M. Del Cima, J. A. Helayël-Neto
Abstract
In this paper, we present a parity-preserving QED3 with spontaneous breaking of a local U(1)-symmetry. The breaking is accomplished by a potential of the 6-type. It is shown that a net attractive interaction appears in the Møller scattering (s and p-wave scattering between two electrons) as mediated by the gauge field and a Higgs scalar. This might favour a pair-condensation mechanism.
