Majorana zero modes in gate-defined germanium hole nanowires
Katharina Laubscher, Jay D. Sau, Sankar Das Sarma
We theoretically study gate-defined one-dimensional channels in planar Ge hole gases as a potential platform for non-Abelian Majorana zero modes. We model the valence band holes in…
Majorana bound states in germanium Josephson junctions via phase control
Melina Luethi, Henry F. Legg, Katharina Laubscher +2
We consider superconductor-normal-superconductor-normal-superconductor (SNSNS) planar Josephson junctions in hole systems with spin-orbit interaction that is cubic in momentum (CSO…
Apparent Kondo effect in Moiré TMD bilayers: Heavy fermions or disorder?
Prathyush P. Poduval, Katharina Laubscher, Sankar Das Sarma
A recent work by Zhao et al. [1] reports the realization of a synthetic Kondo lattice in a gate-tunable Moiré TMD bilayer system. The observation of a Kondo lattice is supported by…
Parity protected superconducting diode effect in topological Josephson junctions
Henry F. Legg, Katharina Laubscher, Daniel Loss +1
In bulk superconductors or Josephson junctions formed in materials with spin-orbit interaction, the critical current can depend on the direction of current flow and applied magneti…
