Abstract

We report detailed measurements of reproducible, aperiodic fluctuations in the magnetoconductance of a submicron, stadium-shaped quantum dot with quantum point contacts. We study the prominent dip at B = 0 that is associated with a ballistic analog of the weak localization effect, and find its properties to be in agreement with semiclassical arguments.
