1. The symmetry multiplets in this case are the Landau levels which are infinitely degenerate. 2. In 1988, it was proposed that there was quantum Hall effect without Landau levels . 3. Each set of wave functions with the same value of is called a Landau level . 4. Then the occupation of each spin Landau level is just the ratio of fluxes =. 5. Semenoff emphasized the occurrence in a magnetic field of an electronic Landau level precisely at the Dirac point. 6. In a magnetic field, their spectrum has a Landau level with energy precisely at the Dirac point. 7. As the magnetic field is increased, more and more electrons can fit into a given Landau level . 8. In general, Landau levels are observed in electronic systems, where = 1 and = 1 / 2. 9. These oscillations arise from the quantization of the semiclassical cyclotron orbits of composite fermions into composite fermion Landau levels . 10. This term then fills in the separation in energy of the different Landau levels , blurring the effect of the quantization.
