Abstract

Scanning gate microscopy measurements in a circular ballistic cavity with a tip placed near its center yield a nonmonotonic dependence of the conductance on the tip voltage. Detailed numerical quantum calculations reproduce these conductance oscillations, and a classical scheme leads to its physical understanding. The large-amplitude conductance oscillations are shown to be of classical origin, and they are well described by the effect of a particular class of short trajectories.
