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…
Determination of the crystal field splitting energy in Cd3As2 using magnetooptics
G. Krizman, T. Schumann, S. Tchoumakov +4
Symmetry considerations are of extreme importance to the topological properties of crystals. A crystal field splitting δ yields Dirac nodes near the Brillouin zone center in Cd3As2…
Magnetic description of the Fermi arc in type-I and type-II Weyl semimetals
Serguei Tchoumakov, Marcello Civelli, Mark O. Goerbig
We consider finite-sized interfaces of a Weyl semi-metal and show that the corresponding confinement potential is similar to the application of a magnetic field. Among the numerous…
