We present an overview of recent advances in the study of energy dynamics and
mechanisms for energy conversion in qubit systems with special focus on realizations in …

We review recent experimental and theoretical work on ultrasmall metallic grains, ie grains
sufficiently small that the conduction electron energy spectrum becomes discrete. The …

A tunable Kondo effect has been realized in small quantum dots. A dot can be switched from
a Kondo system to a non-Kondo system as the number of electrons on the dot is changed …

The ongoing miniaturization of solid state devices often leads to the question:“How small
can we make resistors, transistors, etc., without changing the way they work?” The question …

A generalized quantum master equation theory that governs the exact, nonperturbative
quantum dissipation and quantum transport is formulated in terms of hierarchically coupled …

We study resonant tunneling through a single-level quantum dot in the presence of strong
Coulomb repulsion beyond the perturbative regime. The level is either spin degenerate or …

In this paper, we develop a nonperturbation theory for describing decoherence dynamics of
electron charges in a double quantum dot gated by electrodes. We extend the Feynman …

We develop a theory of electron transport through quantum dots that are weakly coupled to
ferromagnetic leads. The theory covers both the linear and nonlinear transport regimes …

An important class of approaches to the description of electronic transport through
molecules and quantum dots is based on the master equation. We discuss various …

Abstract We study the Fano-Kondo effect in a closed Aharonov-Bohm (AB) interferometer
which contains a single-level quantum dot and predict a frequency doubling of the AB …
