Abstract

We examine the magneto-conductance fluctuations in ballistic quantum dot structures, for a weak field strength, using the recursive Green's function technique. We analyze the spectral content of the conductance fluctuations for two differently shaped dots, where the underlying classical dynamics are either regular or chaotic, by constructing magnetic field conductance correlation functions. We find our numerical quantum mechanical correlation function results for the chaotic dot are in agreement with semiclassical theory predictions.
