The Kondo Effect and Single-electron Transistors

Dr. Andrei Kogan

The discovery of the Kondo effect in single-electron transistors (SETs) a little over 10 years ago generated a tremendous interest in SETs as tunable platforms for studying many-body phenomena. One of these is the Nonequilibrium Kondo effect, which provides insight into the delicate interplay of quantum coherence and dissipation in a strongly interacting system. I will review the basics of the Kondo physics in SETs and then describe recent experiments, in which an externally imposed energy scale is competing with the Kondo correlations: the static effects due to the presence of a Zeeman field, and the non-adiabatic effects due to a high-frequency modulation of the Kondo impurity potential.
