Effects of anisotropy in (2+ 1)-dimensional QED
JA Bonnet, CS Fischer, R Williams - Progress in Particle and Nuclear …, 2012 - Elsevier
We summarize our results for the impact of anisotropic fermionic velocities in (2+ 1)-
dimensional QED on the critical number of fermion flavors, Nfc, and dynamical mass
generation. We apply different approximation schemes for the gauge boson vacuum
polarization and the fermion–boson vertex to analyze the Dyson–Schwinger equations in a
finite volume. Our results point toward large variations of Nfc away from the isotropic point in
agreement with other approaches.
