talkabstract = "We discuss the dynamics of the charge carriers in graphene as the dynamics of fermions on honeycomb lattice.  The screening of Coulomb potential by electrons on sigma-orbitals is taken into account. We present the results of the Monte Carlo study of spontaneous breaking of chiral (sublattice) symmetry in suspended graphene due to electrostatic interaction. potential. We find that suspended graphene is in the conducting phase with unbroken chiral symmetry, agreement with recent experimental results by the Manchester group. By artificially increasing the interaction strength we demonstrate that suspended graphene is quite close to the phase transition associated with spontaneous chiral symmetry breaking, which suggests that the influenec of impurities and external magnetic field might be quite important."
