Direct measurement of spin-flip rates in single-electron tunneling
Olfa Dani, Robert Hussein, Johannes C. Bayer +3
Spin-flips are one of the limiting factors for spin-based information processing. We demonstrate a transport approach for determining the spin-flip rates of a self-assembled InAs d…
Temperature-dependent broadening of coherent current peaks in InAs double quantum dots
Olfa Dani, Robert Hussein, Johannes C. Bayer +2
Quantum systems as used for quantum computation or quantum sensing are nowadays often realized in solid state devices as e.g. complex Josephson circuits or coupled quantum-dot syst…
Machine-learning correction to density-functional crystal structure optimization
Robert Hussein, Jonathan Schmidt, Tomás Barros +2
Density functional theory is routinely applied to predict crystal structures. The most common exchange-correlation functionals used to this end are the Perdew-Burke-Ernzerhof (PBE)…
Resonator induced quantum phase transitions in a hybrid Josephson junction
Robert Hussein, Wolfgang Belzig
We investigate the Josephson current through a suspended carbon nanotube double quantum dot which, at sufficiently low temperatures, is characterized by the ground state of the ele…
Spectral properties of stochastic resonance in quantum transport
Robert Hussein, Sigmund Kohler, Johannes C. Bayer +2
We investigate theoretically and experimentally stochastic resonance in a quantum dot coupled to electron source and drain via time-dependent tunnel barriers. A central finding is…
Phase-controlled spin and charge currents in superconductor-ferromagnet hybrids
Ali Rezaei, Robert Hussein, Akashdeep Kamra +1
We investigate spin-dependent quasiparticle and Cooper-pair transport through a central node interfaced with two superconductors and two ferromagnets. We demonstrate that voltage b…
