Scanning gate experiments: from strongly to weakly invasive probes
R. Steinacher, C. Pöltl, T. Krähenmann +8
An open resonator fabricated in a two-dimensional electron gas is used to explore the transition from strongly invasive scanning gate microscopy to the perturbative regime of weak…
Classical origin of conductance oscillations in an integrable cavity
Christina Pöltl, Aleksey Kozikov, Klaus Ensslin +5
Scanning gate microscopy measurements in a circular ballistic cavity with a tip placed near its center yield a non-monotonic dependence of the conductance on the tip voltage. Detai…
Waiting time distributions for the transport through a quantum dot tunnel coupled to one normal and one superconducting lead
Leila Rajabi, Christina Pöltl, Michele Governale
We have studied the Waiting Time Distributions (WTDs) for sub-gap transport through a single-level quantum dot tunnel coupled to one normal and one superconducting lead. The WTDs r…
Dynamics of interacting transport qubits
Christian Nietner, Gernot Schaller, Christina Pöltl +1
We investigate the electronic transport through two parallel double quantum dots coupled both capacitively and via a perpendicularly aligned charge qubit. The presence of the qubit…
Bunching and anti-bunching in electronic transport
Clive Emary, Christina Pöltl, Alexander Carmele +3
In quantum optics the -function is a standard tool to investigate photon emission statistics. We define a -function for electronic transport and use it to investi…
Feedback stabilization of pure states in quantum transport
Christina Pöltl, Clive Emary, Tobias Brandes
We propose a feedback control scheme for generating and stabilizing pure states of transport devices, such as charge qubits, under non-equilibrium conditions. The purification of t…
Three-level mixing and dark states in transport through quantum dots
Clive Emary, Christina Pöltl, Tobias Brandes
We consider theoretically the transport through the double quantum dot structure of the recent experiment of C. Payette {\it et al.} [Phys. Rev. Lett. {\bf 102}, 026808 (2009)] and…
