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.
