We present a fully electronic analogue of coherent population trapping in quantum optics, based on destructive interference of single-electron tunneling between three quantum dots. A large bias voltage plays the role of the laser illumination. The trapped state is a coherent superposition of the electronic charge in two of these quantum dots, so it is destabilized as a result of decoherence by coupling to external charges. The resulting current I through the device depends on the ratio of the… Expand

Counting statistics of coherent population trapping in quantum dots
Destructive interference of single-electron tunneling between three quantum dots can trap an electron in a coherent superposition of charge on two of the dots. Coupling to external charges causesExpand
Interference through quantum dots
We discuss the effect of quantum interference on transport through a quantum dot (QD) system. We introduce an indirect coherent coupling parameter ?, which provides constructive/destructiveExpand
Coherent population trapping by dark state formation in a carbon nanotube quantum dot
TLDR
All-electronic suppression of transport in a carbon nanotube originating from coherent population trapping is found and criteria for the presence of such a dark state is given. Expand
Coherent and incoherent charge transport in linear triple quantum dots.
TLDR
The findings reveal that the sensitivity to coherence shown by shot noise and skewness, in particular in the limit of large coupling to the drain reservoir, can be used to unambiguously evidence coherent processes involved in charge transport across triple quantum dots. Expand

TLDR
The results show that triple dots in series can be designed to behave as quantum charge rectifiers and include phenomenologically a finite spin relaxation rate and calculate the current numerically. Expand
Gate adjustable coherent three and four level mixing in a vertical quantum dot molecule
We study level mixing in the single-particle energy spectrum of one of the constituent quantum dots in a vertical double quantum dot by performing magneto-resonant-tunneling spectroscopy. The deviceExpand
Electron bunching in triple quantum dot interferometers
We study electron transport through a triple quantum dot in ring or interferometer configuration. In particular, we analyze the influence of a gate voltage that detunes one of the dots, such that itExpand

Phonon-mediated decoherence in triple quantum dot interferometers
We investigate decoherence in a triple quantum dot in ring configuration in which one dot is coupled to a damped phonon mode, while the other two dots are connected to source and drain, respectively.Expand

Current collapse in tunneling transport through benzene.
TLDR
A semiquantitative model for the pi electrons of the benzene is derived that includes general two-body interactions and a current collapse and strong negative differential conductance when the electrode is coupled to the para-position of benzene are predicted. Expand
