Single Spin Transport Spectroscopy - Current Blockade and Spin Decay
Gerold Kiesslich, Gernot Schaller, Clive Emary +1
We present a theory of a single-electron transistor exchange-coupled to a localized spin. We show how to gain detailed quantitative knowledge about the attached spin such as spin s…

Weak coupling approximations in non-Markovian Transport
Philipp Zedler, Gernot Schaller, Gerold Kießlich +2
We study the transport properties of the Fano-Anderson model with a Lorentzian-shaped density of states in one of the electronic reservoirs. We explicitly show that the energy depe…

Systematic Perturbation Theory for Dynamical Coarse-Graining
Gernot Schaller, Philipp Zedler, Tobias Brandes
We demonstrate how the dynamical coarse-graining approach can be systematically extended to higher orders in the coupling between system and reservoir. Up to second order in the co…
