“…It is important to note that recent advances in the lithography of lateral semiconductor QDs have allowed greater control over capacitively coupled DQD systems in parallel or in series. [33][34][35][36][37] This makes it even more relevant to better theoretically understand the effects of capacitive coupling over systems like the one studied in this paper. Only recently has this longrange interaction attracted more widespread attention of experimental and theory groups alike.…”

Capacitively coupled double quantum dot system in the Kondo regime

et al. 2011

A detailed study of the low-temperature physics of an interacting double quantum dot system in a T-shape configuration is presented. Each quantum dot is modeled by a single Anderson impurity and we include an inter-dot electron-electron interaction to account for capacitive coupling that may arise due to the proximity of the quantum dots. By employing a numerical renormalization group approach to a multi-impurity Anderson model, we study the thermodynamical and transport properties of the system in and out of the Kondo regime. We find that the two-stage-Kondo effect reported in previous works is drastically affected by the inter-dot Coulomb repulsion. In particular, we find that the Kondo temperature for the second stage of the two-stage-Kondo effect increases exponentially with the inter-dot Coulomb repulsion, providing a possible path for its experimental observation.

“…This was motivated by a number of reasons. First of all, such three-terminal setups share a number of features with mesoscopic Coulombdrag setups that have been studied both theoretically [60,61,62,63,64,65,66] as well as experimentally [67,68,69,70,71] in the last years. Such Coulomb-drag setups consist of two nearby mesoscopic conductors such as quantum dots.…”

Thermoelectric energy harvesting with quantum dots

Abstract. We review recent theoretical work on thermoelectric energy harvesting in multi-terminal quantum-dot setups. We first discuss several examples of nanoscale heat engines based on Coulomb-coupled conductors. In particular, we focus on quantum dots in the Coulomb-blockade regime, chaotic cavities and resonant tunneling through quantum dots and wells. We then turn towards quantum-dot heat engines that are driven by bosonic degrees of freedom such as phonons, magnons and microwave photons. These systems provide interesting connections to spin caloritronics and circuit quantum electrodynamics.

“…These fluctuations are dominating and it results in positive cross-correlations. A similar effect, the gate-controlled sign reversal of noise cross--correlations, has been found in experiments with double QDs capacitively coupled in parallel in the Coulomb blockade regime [9].…”

“…Our studies are inspired by recent experiments on the shot noise in two quantum dots capacitively coupled [9]. In this paper, we study an influence of dynamical processes, especially a dynamical Coulomb blockade, on an electron bunching and on an enhancement of auto-and cross-correlations.…”

Studies of an enhancement of current shot noises are presented for a device of two large quantum dots coupled capacitively. We analyze current-current correlation functions, and show that a dynamical Coulomb blockade is responsible for an enhancement of the Fano factors. This process can lead also to an electron bunching and positive current cross-correlations. Our theoretical results are discussed in light of recent shot noise experiments.
