Effects of electron interaction on electronic and transport properties of graphene ribbons is unexplored topic to a large extent. In this continuation, focus will be added to effects due to magnetic field, where kinetic energy of electron is quenched. Quantum-mechanical calculations are to be performed. The combined effects of electron-electron interaction and magnetic field on low energy transport in ribbons of different crystallographic orientation is to be explored. A challenge here is the self-consistent calculations to obtain charge densities and potentials when a system is doped with external charges. The method previously developed will be improved to tackle strong magnetic fields. To perform calculations the computational resources are required.
