Classical origin of conductance oscillations in an integrable cavity
arXiv:1603.00704 · doi:10.1103/PhysRevB.94.195304
Abstract
Scanning gate microscopy measurements in a circular ballistic cavity with a tip placed near its center yield a non-monotonic 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 well described by the effect of a particular class of short trajectories.
