Abstract :
We study the anomalous quantum Hall effect exhibited by the relativistic particles living on two-sphere image and submitted to a magnetic monopole. We start by establishing a direct connection between the Dirac and Landau operators through the Pauli–Schrödinger Hamiltonian image. This will be helpful in the sense that the Dirac eigenvalues and eigenfunctions will be easily derived. In analyzing image spectrum, we show that there is a composite fermion nature supported by the presence of two effective magnetic fields. For the lowest Landau level, we argue that the basic physics of graphene is similar to that of two-dimensional electron gas, which is in agreement with the planar limit. For the higher Landau levels, we propose a image wavefunction for different filling factors that captures all symmetries. Focusing on the graphene case, i.e. image, we give different configurations those allowed to recover some known results.
