Kondo Effect and Phase Measurement in Double Quantum Dot in Parallel

Y Zhang, R Sakano, M Eto - Journal of the Physical Society of Japan, 2022 - journals.jps.jp
We propose a double quantum dot (DQD) in parallel as a tractable model for a mesoscopic
ring with an embedded quantum dot (QD), which functions as a QD interferometer. One of …

Bipolaronic blockade effect in quantum dots with negative charging energy

TF Fang, SF Zhang, CJ Niu, Q Sun - Europhysics Letters, 2014 - iopscience.iop.org
We investigate single-electron transport through quantum dots with negative charging
energy induced by a polaronic energy shift. For weak dot-lead tunnel couplings, we …

Charge-Kondo effect mediated by repulsive interactions

SM Tabatabaei - Physical Review B, 2018 - APS
We investigate the Kondo effect in a double quantum dot which is capacitively coupled to a
charge qubit. It is shown that due to this capacitive coupling, the bare interdot repulsive …

Spin accumulation assisted by the Aharonov-Bohm-Fano effect of quantum dot structures

WJ Gong, Y Han, GZ Wei, A Du - Nanoscale research letters, 2012 - Springer
Abstract We investigate the spin accumulations of Aharonov-Bohm interferometers with
embedded quantum dots by considering spin bias in the leads. It is found that regardless of …

Tunable spin manipulation in a quantum dot embedded in an Aharonov-Bohm interferometer

C Jiang, WJ Gong, GZ Wei - Journal of Applied Physics, 2012 - pubs.aip.org
In this paper, we study the electron properties of an Aharonov-Bohm interferometer with an
embedded quantum dot (QD) by considering the leads of spin bias. As a result, it is found …

From the Kondo box problem to the physics of the Kondo-lattice box

A Schwabe - 2013 - ediss.sub.uni-hamburg.de
The Kondo effect, the screening of the spin of an impurity by the conduction electrons of a
metallic host system, is a standard problem in solid state physics. At weak coupling strengths …
