Physics of lateral triple quantum-dot molecules with controlled electron numbers

CY Hsieh, YP Shim, M Korkusinski… - Reports on Progress in …, 2012 - iopscience.iop.org
We review the recent progress in theory and experiments with lateral triple quantum dots
with controlled electron numbers down to one electron in each dot. The theory covers …

The one-dimensional Wigner crystal in carbon nanotubes

VV Deshpande, M Bockrath - Nature Physics, 2008 - nature.com
A dilute system of electrons interacting through long-range Coulomb forces has been
predicted to form a periodic solid known as a Wigner crystal. To date, this state has been …

Electrostatically defined serial triple quantum dot charged with few electrons

A serial triple quantum dot (TQD) electrostatically defined in a Ga As∕ Al Ga As
heterostructure is characterized by using a nearby quantum point contact as charge …

Fano-Kondo effect in side-coupled double quantum dots at finite temperatures and the importance of two-stage Kondo screening

R Žitko - Physical Review B—Condensed Matter and Materials …, 2010 - APS
We study the zero-bias conductance through the system of two quantum dots, one of which
is embedded directly between the source and drain electrodes, while the second dot is side …

Multiple-impurity Anderson model for quantum dots coupled in parallel

R Žitko, J Bonča - Physical Review B—Condensed Matter and Materials …, 2006 - APS
The system of several (N) quantum dots coupled in parallel to the same single-mode
conduction channel can be modeled as a single-channel N-impurity Anderson model. Using …

Quantum phase transition in quantum dot trimers

AK Mitchell, TF Jarrold, DE Logan - Physical Review B—Condensed Matter …, 2009 - APS
We investigate a system of three tunnel-coupled semiconductor quantum dots in a triangular
geometry, one of which is connected to a metallic lead, in the regime where each dot is …

Topological Hunds rules and the electronic properties of a triple lateral quantum dot molecule

M Korkusinski, IP Gimenez, P Hawrylak… - Physical Review B …, 2007 - APS
We analyze theoretically and experimentally the electronic structure and charging diagram
of three coupled lateral quantum dots filled with electrons. Using the Hubbard model and …

Functional renormalization group approach to transport through correlated quantum dots

C Karrasch, T Enss, V Meden - Physical Review B—Condensed Matter and …, 2006 - APS
We investigate the effect of local Coulomb correlations on electronic transport through a
variety of coupled quantum dot systems connected to Fermi liquid leads. We use a functional …

Kondo screening cloud in the single-impurity Anderson model: A density matrix renormalization group study

A Holzner, IP McCulloch, U Schollwöck, J von Delft… - Physical Review B …, 2009 - APS
A magnetic moment in a metal or in a quantum dot is, at low temperatures, screened by the
conduction electrons through the mechanism of the Kondo effect. This gives rise to spin-spin …

A triple quantum dot in a single-wall carbon nanotube

K Grove-Rasmussen, HI Jørgensen, T Hayashi… - Nano Letters, 2008 - ACS Publications
A top-gated single-wall carbon nanotube is used to define three coupled quantum dots in
series between two electrodes. The additional electron number on each quantum dot is …
