Abstract

The transport in large, and strongly open, quantum dots, which might typically be viewed as lying well within the semiclassical regime, was studied. It was found that the low-temperature magnetoresistance of these structures exhibits regular fluctuations, with just a small number of dominant frequency components, indicative of the presence of dynamical tunneling into regular orbits. Results suggest that dynamical tunneling may apply a more generic role in transport through mesoscopic structures than has thus far been appreciated.
