Position operators and interband matrix elements of scalar and vector potentials in the 8-band Kane model
I. A. Ado, M. Titov, Rembert A. Duine +1
We diagonalize the 8-band Kane Hamiltonian with a proper inclusion of the interband matrix elements of the scalar and vector potentials. This leads, among other results, to a modif…

Kubo formula for dc conductivity: generalization to systems with spin-orbit coupling
I. A. Ado, M. Titov, Rembert A. Duine +1
We revise the Kubo formula for the electric dc conductivity in the presence of spin-orbit coupling (SOC). We discover that each velocity operator that enters this formula differs f…
