By exploiting our recently derived exact formula for the Lindhard polarization function in the presence of
Bychkov-Rashba BR and Dresselhaus D spin-orbit interaction SOI, we show that the interplay of different
SOI mechanisms induces highly anisotropic modifications of the static dielectric function. We find that under
certain circumstances the polarization function exhibits doubly singular ...
