Stability of Majorana modes in Coulomb-disordered topological insulator nanowires
Leonard Kaufhold, Achim Rosch
We evaluate theoretically the possibility to realize Majorana zero modes in hybrid devices made from topological-insulator (TI) nanowires proximity-coupled to a superconductor. Suc…
Probing the spin polarization of an Anderson impurity
Mahasweta Bagchi, Tfyeche Y. Tounsi, Affan Safeer +6
We report spin-polarized scanning tunneling microscopy measurements of an Anderson impurity system in MoS mirror twin boundaries, where both the quantum confined impurity sta…
Modulated Kondo screening along magnetic mirror twin boundaries in monolayer MoS2 on graphene
Camiel van Efferen, Jeison Fischer, Theo A. Costi +3
A many-body resonance emerges at the Fermi energy when an electron bath screens the magnetic moment of a half-filled impurity level. This Kondo effect, originally introduced to exp…
Nonlinear conductance of long quantum wires at a conductance plateau transition: Where does the voltage drop?
T. Micklitz, A. Levchenko, A. Rosch
We calculate the linear and nonlinear conductance of spinless fermions in clean, long quantum wires where short-ranged interactions lead locally to equilibration. Close to the quan…
Non-equilibrium conductance of a three-terminal quantum dot in the Kondo regime: Perturbative Renormalization Group
N. Shah, A. Rosch
Motivated by recent experiments, we consider a single-electron transistor in the Kondo regime which is coupled to three leads in the presence of large bias voltages. Such a steady-…
Mesoscopic effects in tunneling between parallel quantum wires
Daniel Boese, Michele Governale, A. Rosch +1
We consider a phase-coherent system of two parallel quantum wires that are coupled via a tunneling barrier of finite length. The usual perturbative treatment of tunneling fails in…
