Description

We present results from our lattice simulation of parity-invariant three-dimensional QED with two dynamical flavors of massless two-component fermions, implemented using the overlap operator. Contradictory to the expectation from various plausibility arguments, we find evidences from the finite-size scaling of eigenvalues of the Dirac operator and from correlators of fermion bilinears, for the two flavor theory to be scale-invariant with the mass anomalous dimension close to 1, the maximum allowed value for a conformal field theory.
