(Left) The energy spectrum of the flat band when magnetic field is absent. There is no available energy state within the band gap. (Right) The energy spectrum under magnetic field (the Landau levels) arising from the flat band. The Landau levels are spread into the gapped region and the width of the Landau level spreading is determined by the quantum distance of the Bloch states of the flat band.
