Magnetoconductivity of a disordered electron system with n orbitals persite
In the absence of a magnetic field, two formally equivalent expressions for the conductivity contribute different sets of Feynman diagrams, due to cancellations. We use this result to calculate the magnetoconductivity of the N-orbital model to 0(1/N) and we show that it coincides with the result for...

| Sumario: | In the absence of a magnetic field, two formally equivalent expressions for the conductivity contribute different sets of Feynman diagrams, due to cancellations. We use this result to calculate the magnetoconductivity of the N-orbital model to 0(1/N) and we show that it coincides with the result for a single-level system. |
