Description

We present the first numerical evidence of Gribov copies on a lattice. Photon propagators are numerically studied under the non-linear gauge condition dμ sin θμ=0, where θμ's are gauge potentials defined on a lattice. It is shown that this standard lattice Landau gauge condition is not unique. In the Coulomb phase a correct free propagator is obtained only after removing this ambiguity. (orig.)
