Abstract
We study electron transport through single and double quantumdots with large level spacing and charging energy. Motivatedby recent experiments we focus on linear and nonlinearresponse of two model systems: a single dot with two levelsand a capacitively coupled double dot. At low temperature andstrong coupling to the leads, quantum fluctuations and Kondo-like many-body effects become important and show up, e.g., asresonances in the current-voltage characteristics. Inparticular, we propose a way to observe the splitting of theKondo peak as a function of the applied bias voltage.
