Kurzbeschreibung (Abstract)
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.
