Critical scaling of finite temperature QED3 in anisotropic space-time

We investigate the scaling behavior of the critical temperature of anisotropic QED in 2+1 dimensions with respect to a variation of the number of fermions Nf. To this end we determine the order parameter of the chiral transition of the theory from a set of (truncated) Dyson-Schwinger equations for the fermion propagator formulated in a finite volume. We verify the validity of previously determined universal power laws for the scaling behavior of the critical temperature with Nf. We furthermore study the variation of the corresponding critical exponent with the degree of anisotropy and find considerable variations.
