Fermion propagators in QED 3 with velocity anisotropies

QED3 with fermi and gap anisotropies is considered to be a candida te effective field theory of high temperature superconductors. Simulations of a varian t of the theory have demonstrated that there is evidence consistent with a phase transition to a chi r lly restored phase as the velocity anisotropy increases, and that the correlation lengths of p ions in… (More)
