Double island Coulomb blockade in (Ga,Mn)As-nanoconstrictions
S. Geißler, S. Pfaller, M. Utz +4
We report on a systematic study of the Coulomb blockade effects in nanofabricated narrow constrictions in thin (Ga,Mn)As films. Different low-temperature transport regimes have bee…

Sub-gap spectroscopy of thermally excited quasiparticles in a Nb contacted carbon nanotube quantum dot
M. Gaass, S. Pfaller, T. Geiger +4
We present electronic transport measurements of a single wall carbon nanotube quantum dot coupled to Nb superconducting contacts. For temperatures comparable to the superconducting…

Subgap features due to quasiparticle tunneling in quantum dots coupled to superconducting leads
Sebastian Pfaller, Andrea Donarini, Milena Grifoni
We present a microscopic theory of transport through quantum dot set-ups coupled to superconducting leads. We derive a master equation for the reduced density matrix to lowest orde…
