Description
There are plausibility arguments that QED in three dimensions has
a critical number of flavors of massless two-component fermions,
below which scale invariance is broken by the presence of bilinear
condensate. We present numerical evidences from our dynamical
lattice simulations using overlap as well as Wilson-Dirac fermions
for the absence of bilinear condensate using the following methods:
finite-size scaling analysis of the low-lying eigenvalues of the Dirac
operator, comparison of the eigenvalue distributions to the non-chiral
random matrix theory, and by checking if the inverse participation
ratio and number variance show ergodic behavior.
