Quantum Mechanical Derivation of the Classical Drude-Like Optical Conductivity Tensor of the Free Electron System in an Uniform Magnetic Field

抄録

The classical Drude-like optical conductivity tensor of the free electron systemin an uniform magnetic field is derived from the quantum mechanical Kuboformula. In the derivation, the exact solution for the free electron by Landauis used, although the interactions giving the scattering of the electron such asthe electron-phonon interaction are taken into account as a phenomenologicallife time effect.
