Full counting statistics of super-Poissonian shot noise in multilevel quantum dots

W Belzig - Physical Review B—Condensed Matter and Materials …, 2005 - APS
We examine the full counting statistics of quantum dots, which display super-Poissonian
shot noise. By an extension to a generic situation with many excited states we identify the …

Waiting times and noise in single particle transport

T Brandes - Annalen der Physik, 2008 - Wiley Online Library
The waiting time distribution w (τ), ie the probability for a delay τ between two subsequent
transition ('jumps') of particles, is a statistical tool in (quantum) transport. Using generalized …

Noise enhancement due to quantum coherence in coupled quantum dots

G Kießlich, E Schöll, T Brandes, F Hohls, RJ Haug - Physical review letters, 2007 - APS
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 …

Current noise in a vibrating quantum dot array

C Flindt, T Novotný, AP Jauho - Physical Review B—Condensed Matter and …, 2004 - APS
We develop methods for calculating the zero-frequency noise for quantum shuttles, ie,
nanoelectromechanical devices where the mechanical motion is quantized. As a model …

Tunable noise cross correlations in a double quantum dot

DT McClure, L DiCarlo, Y Zhang, HA Engel… - Physical review …, 2007 - APS
We report measurements of the cross correlation between temporal current fluctuations in
two capacitively coupled quantum dots in the Coulomb blockade regime. The sign of the …

Positive cross-correlations due to dynamical channel blockade in a three-terminal quantum dot

A Cottet, W Belzig, C Bruder - Physical Review B—Condensed Matter and …, 2004 - APS
We investigate current fluctuations in a three-terminal quantum dot in the sequential
tunneling regime. In the voltage-bias configuration chosen here, the circuit is operated as a …

Super-Poissonian noise, negative differential conductance, and relaxation effects in transport through molecules, quantum dots, and nanotubes

A Thielmann, MH Hettler, J König, G Schön - Physical Review B—Condensed …, 2005 - APS
We consider charge transport through a nanoscopic object, eg, single molecules, short
nanotubes, or quantum dots, that is weakly coupled to metallic electrodes. We account for …

Transport statistics of interacting double dot systems: Coherent and non-Markovian effects

G Schaller, G Kießlich, T Brandes - Physical Review B—Condensed Matter and …, 2009 - APS
We formalize the derivation of a generalized coarse-graining n-resolved master equation by
introducing a virtual detector counting the number of transferred charges in single-electron …

Nonequilibrium entanglement and noise in coupled qubits

N Lambert, R Aguado, T Brandes - Physical Review B—Condensed Matter and …, 2007 - APS
We study the charge entanglement and noise spectrum of two Coulomb-coupled double
quantum dots under stationary nonequilibrium transport conditions. In the transport regime …

Frequency-dependent current noise through quantum-dot spin valves

M Braun, J König, J Martinek - Physical Review B—Condensed Matter and …, 2006 - APS
We study frequency-dependent current noise through a single-level quantum dot connected
to ferromagnetic leads with noncollinear magnetization. We propose to use the frequency …
