[Wien] Ask for help

  Dear Pavel,
Thank for your reply,
In the dielectric function expression the wave vector of light q is much
smaller than any typical wave vector of electrons in the system, it can be
evaluated for small  q by k · p perturbation theory.(check this reference
please ;AMBROSCH-DRAXL, Claudia et SOFO, Jorge O. Linear optical properties
of solids within the full-potential linearized augmented planewave
method. *Computer
physics communications*, 2006, vol. 175, no 1, p. 1-14.)
I want know these values of wave vector of light q .
Best regards
Siham
