Reverse quantum state engineering using electronic feedback loops
Gerold Kiesslich, Clive Emary, Gernot Schaller +1
We propose an all-electronic technique to manipulate and control interacting quantum systems by unitary single-jump feedback conditioned on the outcome of a capacitively coupled el…
Transport and semiclassical dynamics of coupled quantum dots interacting with a local magnetic moment
Klemens Mosshammer, Gerold Kiesslich, Tobias Brandes
We present a theory of magnetotransport through a system of two coupled electronic orbitals, where the electron spin interacts with a (large) local magnetic moment via an exchange…
Probing the power of an electronic Maxwell Demon
Gernot Schaller, Clive Emary, Gerold Kiesslich +1
We suggest that a single-electron transistor continuously monitored by a quantum point contact may function as a Maxwell demon when closed-loop feedback operations are applied as t…
Limit-Cycles and Chaos in the Current Through a Quantum Dot
Carlos López-Monís, Clive Emary, Gerold Kiesslich +2
We investigate non-linear magneto-transport through a single level quantum dot coupled to ferromagnetic leads, where the electron spin is coupled to a large, external (pseudo)spin…
Charge Qubit Purification by an Electronic Feedback Loop
G. Kiesslich, G. Schaller, C. Emary +1
We propose the manipulation of an isolated qubit by a simple instantaneous closed-loop feedback scheme in which a time-dependent electronic detector current is directly back-couple…
A low-dimensional detector model for full counting statistics: Trajectories, Back-Action, and Fidelity
Gernot Schaller, Gerold Kiesslich, Tobias Brandes
We study the combined counting statistics of two capacitively coupled transport channels. In particular, we examine the conditions necessary for utilizing one channel as detector s…
Counting Statistics in Multi-stable Systems
Gernot Schaller, Gerold Kießlich, Tobias Brandes
Using a microscopic model for stochastic transport through a single quantum dot that is modified by the Coulomb interaction of environmental (weakly coupled) quantum dots, we deriv…
Transport Statistics of Interacting Double Dot Systems: Coherent and Non-Markovian Effects
Gernot Schaller, Gerold Kiesslich, Tobias Brandes
We formalize the derivation of a generalized coarse-graining -resolved master equation by introducing a virtual detector counting the number of transferred charges in single-ele…
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…
Noise enhancement due to quantum coherence in coupled quantum dots
G. Kiesslich, E. Schoell, T. Brandes +2
We show that the intriguing observation of noise enhancement in the charge transport through two vertically coupled quantum dots can be explained by the interplay of quantum cohere…
Counting statistics and decoherence in coupled quantum dots
G. Kiesslich, P. Samuelsson, A. Wacker +1
We theoretically consider charge transport through two quantum dots coupled in series. The corresponding full counting statistics for noninteracting electrons is investigated in th…
Coulomb effects in tunneling through a quantum dot stack
H. Sprekeler, G. Kiesslich, A. Wacker +1
Tunneling through two vertically coupled quantum dots is studied by means of a Pauli master equation model. The observation of double peaks in the current-voltage characteristic in…
Positive Correlations in Tunneling through coupled Quantum Dots
H. Sprekeler, G. Kiesslich, A. Wacker +1
Due to the Fermi-Dirac statistics of electrons the temporal correlations of tunneling events in a double barrier setup are typically negative. Here, we investigate the shot noise b…

The low-frequency shot noise properties of two electrostatically coupled semiconductor quantum dot states which are connected to emitter/collector contacts are studied. A master eq…

G. Kießlich, A. Wacker, E. Schöll
The transmission through quantum wires is studied within a noninteracting model taking into account the geometry of cleaved edge overgrowth devices. We show that the junction betwe…
