We report on the direct numerical measurements of the conductivity of graphene monolayer. Our numerical simulations are performed in the effective lattice field theory with noncompact 3+1-dimensional Abelian lattice gauge fields and 2+1-dimensional staggered lattice fermions. The conductivity is obtained from the Green-Kubo relations using the maximum entropy method. We find that in a phase with spontaneously broken sublattice symmetry the conductivity rapidly decreases. For the largest value of the coupling constant used in our simulations g=4.5, the dc conductivity is less than the dc conductivity in the weak-coupling phase (at g<3.5) by at least three orders of magnitude.
