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…
Interplay of Coulomb repulsion and spin-orbit coupling in superconducting 3D quadratic band touching Luttinger semimetals
Serguei Tchoumakov, Louis J. Godbout, William Witczak-Krempa
We investigate the superconductivity of 3D Luttinger semimetals, such as YPtBi, where Cooper pairs are constituted of spin-3/2 quasiparticles. Various pairing mechanisms have alrea…
Superconductivity from Coulomb repulsion in three-dimensional quadratic band touching Luttinger semimetals
Serguei Tchoumakov, Louis J. Godbout, William Witczak-Krempa
We study superconductivity driven by screened Coulomb repulsion in three-dimensional Luttinger semimetals with a quadratic band touching and strong spin-orbit coupling. In these se…
