dc.description.abstract
In nonmagnetic crystals with inversion symmetry the electronic bands are
twofold degenerate. As a consequence, any orthonormalized linear combination
of the two corresponding eigenfunctions can represent the electron wave
function. A priori it is not obvious which superposition, gauge, should be
chosen to calculate a quantity which is not gauge invariant within a certain
approximation. Here we consider gauge options appropriate under particular
physical conditions.
