Impurities in 3D quadratic band-touching Luttinger semimetals : Friedel and RKKY oscillations
Louis J. Godbout, Serguei Tchoumakov, William Witczak-Krempa
We investigate the response of 3D Luttinger semimetals to localized charge and spin impurities as a function of doping. The strong spin-orbit coupling of these materials strongly i…
