Transcendental momentum quantization in semiconducting Rashba nanowires and zero energy states in their normal and superconducting phase
Nico Leumer, Harald Schmid, Milena Grifoni +1
We study finite system properties of the canonical low energy model for a semiconducting nanowire with Rashba spin-orbit coupling. The case of an isolated wire as well as of one pr…
Sources of negative tunneling magneto-resistance in multilevel quantum dots with ferromagnetic contacts
S. Koller, J. Paaske, M. Grifoni
We analyze distinct sources of spin-dependent energy level shifts and their impact on the tunneling magnetoresistance (TMR) of interacting quantum dots coupled to collinearly polar…
Graphene armchair nanoribbon single-electron transistors: The peculiar influence of end states
Sonja Koller, Leonhard Mayrhofer, Milena Grifoni
We present a microscopic theory for interacting graphene armchair nanoribbon quantum dots. Long range interaction processes are responsible for Coulomb blockade and spin-charge sep…
Correlated sequential tunneling through a double barrier for interacting one-dimensional electrons
M. Thorwart, R. Egger, M. Grifoni
The problem of resonant tunneling through a quantum dot weakly coupled to spinless Tomonaga-Luttinger liquids has been studied. We compute the linear conductance due to sequential…
