Charge and Spin Transport and Symmetry Broken State in Graphene

We reproduce the recent experimentally discovered odd integer quantum Hall effect in graphene The bottom image reveals a stripe order and symmetry broken state in higher Dirac Landau levels Small projects involved in this research are used in a new course taught at CSUN by Dr. Sheng (PHYS 466) for undergraduate students, where density of states, edge states, and effect of Hubbard interaction for electrons were looked at by students in class.
