Quantum stochastic resonance in a single-photon emitter
H. Mannel, J. Zöllner, E. Kleinherbers +8
Stochastic resonance is a phenomenon in which fluctuations enhance an otherwise weak signal. It has been found in many different systems in paleoclimatology, biology, medicine, and…
Effective time-dependent temperature for fermionic master equations beyond the Markov and the secular approximations
Lukas Litzba, Eric Kleinherbers, Jürgen König +2
We consider a fermionic quantum system exchanging particles with an environment at a fixed temperature and study its reduced evolution by means of a Redfield-I equation with time-d…
Dark versus blocking states in electronic transport: a Lee-Yang zero analysis of full counting statistics
Johann Zöllner, Philipp Stegmann, Jürgen König +1
Electronic transport through nanostructures can be suppressed by coherent population trapping, in which quantum coherence leads to a dark state that decouples from the drain electr…
Unraveling spin dynamics from charge fluctuations
Eric Kleinherbers, Hendrik Mannel, Jens Kerski +3
The use of single electron spins in quantum dots as qubits requires detailed knowledge about the processes involved in their initialization and operation as well as their relaxatio…
Full counting statistics in a Majorana single-charge transistor
Eric Kleinherbers, Alexander Schünemann, Jürgen König
We study full counting statistics of electron transport through a Majorana single-charge transistor. At low bias voltage, transport is dominated by the so-called Josephson-Majorana…
Electronic transport in bent carbon nanotubes
Eric Kleinherbers, Thomas Stegmann, Nikodem Szpak
We study the electronic transport through uniformly bent carbon nanotubes. For this purpose, we describe the nanotube with the tight-binding model and calculate the local current f…
Post-processing of real-time quantum event measurements for an optimal bandwidth
Jens Kerski, Hendrik Mannel, Pia Lochner +7
Single electron tunneling and its transport statistics have been studied for some time using high precision charge detectors. However, this type of detection requires advanced lith…
Synchronized coherent charge oscillations in coupled double quantum dots
Eric Kleinherbers, Philipp Stegmann, Jürgen König
We study coherent oscillations in double quantum dots tunnel-coupled to metallic leads by means of full counting statistics of electron transport. If two such systems are coupled b…
Pushing the limits in real-time measurements of quantum dynamics
Eric Kleinherbers, Philipp Stegmann, Annika Kurzmann +3
Time-resolved studies of quantum systems are the key to understand quantum dynamics at its core. The real-time measurement of individual quantum numbers as they switch between cert…
Relaxation dynamics in a Hubbard dimer coupled to fermionic baths: phenomenological description and its microscopic foundation
Eric Kleinherbers, Nikodem Szpak, Jürgen König +1
We study relaxation dynamics in a strongly-interacting two-site Fermi-Hubbard model that is induced by coupling each site to a local fermionic bath. To derive the proper form of th…
Revealing attractive electron-electron interaction in a quantum dot by full counting statistics
Eric Kleinherbers, Philipp Stegmann, Jürgen König
Recent experiments [Nature 521, 196 (2015) and Nat. Commun. 8, 395 (2017)] have presented evidence for electron pairing in a quantum dot beyond the superconducting regime. Here, we…
