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…
Higher-Order Photon Statistics as a New Tool to Reveal Hidden Excited States in a Plasmonic Cavity
Philipp Stegmann, Satyendra Nath Gupta, Gilad Haran +1
Among the best known quantities obtainable from photon correlation measurements are the ~correlation functions. Here, we introduce a new procedure to evaluate these correl…
Statistical analysis of spin switching in coupled spin-crossover molecules
Philipp Stegmann, Alex Gee, Neil T. Kemp +1
We study the switching behavior of two spin-crossover molecules residing in a nanojunction device consisting of two closely spaced gold electrodes. The spin states are monitored th…
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…
Independent and coherent transitions between antiferromagnetic states of few-molecule systems
Claire Besson, Philipp Stegmann, Michael Schnee +12
Spin-electronic devices are poised to become part of mainstream microelectronic technology .Downsizing them, however, faces the intrinsic difficulty that as ferromagnets become sma…
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…
Electron Waiting Times in a Strongly Interacting Quantum Dot: Interaction Effects and Higher-Order Tunneling Processes
Philipp Stegmann, Björn Sothmann, Jürgen König +1
Distributions of electron waiting times have been measured in several recent experiments and have been shown to provide complementary information compared to what can be learned fr…
Real-time detection of every Auger recombination in a self-assembled quantum dot
Pia Lochner, Annika Kurzmann, Jens Kerski +6
Auger recombination is a non-radiative process, where the recombination energy of an electron-hole pair is transferred to a third charge carrier. It is a common effect in colloidal…
Relaxation dynamics in double-spin systems
Philipp Stegmann, Jürgen König, Björn Sothmann
We consider the relaxation dynamics of two spins coupled to a common bosonic bath. The time evolution is simulated by a generalized master equation derived within a real-time diagr…
Iterative path-integral summations for the tunneling magnetoresistance in interacting quantum-dot spin valves
S. Mundinar, P. Stegmann, J. König +1
We report on the importance of resonant-tunneling processes on quantum transport through interacting quantum-dot spin valves. To include Coulomb interaction in the calculation of t…
Optical detection of single electron transport dynamics
A. Kurzmann, P. Stegmann, J. Kerski +6
The unpredictability of a single quantum event lies at the very core of quantum mechanics. Physical information is therefore drawn from a statistical evaluation of many such proces…
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…
Coherent dynamics in stochastic systems revealed by full counting statistics
Philipp Stegmann, Jürgen König, Stephan Weiss
Stochastic systems feature, in general, both coherent dynamics and incoherent transitions between different states. We propose a method to identify the coherent part in the full co…
Inverse counting statistics based on generalized factorial cumulants
Philipp Stegmann, Jürgen König
We propose a procedure to reconstruct characteristic features of an unknown stochastic system from the long-time full counting statistics of some of the system's transitions that a…
Violation of detailed balance for charge-transfer statistics in Coulomb-blockade systems
Philipp Stegmann, Jürgen König
We discuss the possibility to generate in Coulomb-blockade systems steady states that violate detailed balance. This includes both voltage biased and non-biased scenarios. The viol…
Short-time counting statistics of charge transfer in Coulomb-blockade systems
Philipp Stegmann, Jürgen König
We study full counting statistics of electron tunneling in Coulomb-blockade systems in the limit of short measuring-time intervals. This limit is particularly suited to identify co…
Detection of interactions via generalized factorial cumulants in systems in and out of equilibrium
Philipp Stegmann, Björn Sothmann, Alfred Hucht +1
We introduce time-dependent, generalized factorial cumulants of the full counting statistics of electron transfer as a tool to detect interactions in nanostructures. The…
