We study the transport behavior induced by a small bias voltage through a quantum dot connected to one-channel disordered wires by means of a quantum Monte Carlo method. We model the quantum dot by the Hubbard-Anderson ...

© 2016 Elsevier Inc.The use of bacterial cells to produce fluorescent semiconductor nanoparticles (quantum dots, QDs) represents a green alternative with promising economic potential. In the present work, we report for the ...

We present a way to manipulate an electron trapped in a layered quantum dot based on near-threshold properties of one-body potentials. First, we show that potentials with a simple global parameter allow the manipulation ...

In the present study, we review the one-qubit dynamics and we offer a new unifying interpretation of the Landau-Zenner and the Rabi dynamics, by indicating the physical elements responsible for the manifestation of one ...

We study the thermopower, thermal conductance, electric conductance and the thermoelectric figure of merit for a gate-defined T-shaped single quantum dot (QD). The QD is solved in the limit of strong Coulombian repulsion ...

In this work we present a model qubit whose basis states are eigenstates of a multilayered quantum dot. We show that the proper design of the quantum dot results in qubit states that have excellent dynamical properties ...

The properties of excitons formed in spherical quantum dots are studied using the k⋅p method within the Hartree approximation. The spherical quantum dots considered have a central core and several concentric layers of ...

The ground and excited states of a donor impurity at the center of a spherical quantum dot subject to a magnetic field are calculated within the effective-mass approximation. The barriers are infinitely high and the ...

We report a numerical renormalization-group study of the thermoelectric effect in the single-electron transistor (SET) and side-coupled geometries. As expected, the computed thermal conductance and thermopower curves show ...
