Query: Combined effects of disorders and electron-electron interactions upon
  metal-insulator transition in 2D non-bipartite lattice   We examined the characteristics of a metal-insulator transition on a
two-dimensional non-bipartite lattice when both disorders and electron
interactions are present. Using a real-space renormalization group method and
finite-size scaling analysis we have found that after the disordered system
transits from the insulating state to the metal one, it can reenter an
insulating state if there is a further increase in the electron-electron
interactions.
