While free electron model specifically deals with electrons, a plasma generally consists of both electrons and positively ionized atoms.

As a follow up to the previous question. While deriving optical processes in semiconductors practically all textbooks use the vector potential and the electron momentum (A.p). I haven;t found a single reference that actually uses the electric dipole moment to do this and yet this is the value...

When using k.p theory to calculate the magnitude of the electric dipole moment in semiconductors for band-to-band transitions, the value of the dipole moment is basically fitted to the effective mass of the electron in the conduction band. However, the values turn out to be larger than the...
