Dynamics of coupled spins in quantum dots with strong spin-orbit interaction
A. Pfund, I. Shorubalko, K. Ensslin +1
We investigated the time dependence of two-electron spin states in a double quantum dot fabricated in an InAs nanowire. In this system, spin-orbit interaction has substantial influ…
Pauli spin-blockade in an InAs nanowire double quantum dot
A. Pfund, I. Shorubalko, R. Leturcq +1
We measure transport at finite bias through a double quantum dot formed by top-gates in an InAs nanowire. Pauli spin-bockade is confirmed with several electrons in the dot. This is…
Spin state mixing in InAs double quantum dots
A. Pfund, I. Shorubalko, K. Ensslin +1
We quantify the contributions of hyperfine and spin-orbit mediated singlet-triplet mixing in weakly coupled InAs quantum dots by electron transport spectroscopy in the Pauli spin b…
Suppression of spin relaxation in an InAs nanowire double quantum dot
A. Pfund, I. Shorubalko, K. Ensslin +1
We investigate the triplet-singlet relaxation in a double quantum dot defined by top-gates in an InAs nanowire. In the Pauli spin blockade regime, the leakage current can be mainly…
Tunable few electron quantum dots in InAs nanowires
I. Shorubalko, A. Pfund, R. Leturcq +5
Quantum dots realized in InAs are versatile systems to study the effect of spin-orbit interaction on the spin coherence, as well as the possibility to manipulate single spins using…
Coherent spin ratchets: A spin-orbit based quantum ratchet mechanism for spin-polarized currents in ballistic conductors
Matthias Scheid, Andreas Pfund, Dario Bercioux +1
We demonstrate that the combined effect of a spatially periodic potential, lateral confinement and spin-orbit interaction gives rise to a quantum ratchet mechanism for spin-polariz…
