  We investigate the electronic properties of the parabolic Dirac system. In
the pres- ence of magnetic field, we discuss the thermodynamical potential and
the anomalous diamagnetism due to the presence of Dirac cone. The integer Hall
conductivity and the intrinsic Hall conductivity induced by the Berry curvature
are also investigated. Considering the disorder-induced self-energy in
self-consistent Born approximation, the RKKY interaction, long-range scattering
rate and the spectral function are also calculated, which are distinct to that
of the clean system (without impurity).
