Magnetic oscillations in planar systems with the Dirac-like spectrum of quasiparticle excitations. II. Transport properties

The quantum magnetic oscillations of electrical (Shubnikov-de Haas effect) and thermal conductivities are studied for graphene which represents a distinctive example of planar systems with a linear, Dirac-like spectrum of quasiparticle excitations. We show that if utmost care is taken to separate electron and phonon contributions in the thermal conductivity, the oscillations of electron thermal conductivity kappa(B) and Lorenz number, L(B) would be observable in the low-field (less than a few teslas) regime.
