Abstract

A general capacitative model for an antidot which had two localized edge states with different spins in the quantum Hall regime was discussed. It was assumed that antidot potential varies linearly within the scale of the magnetic length. It was found that the capacitative coupling of localized excess charges, which were generated around the antidot due to magnetic flux quantization, and their effective spin fluctuations resulted in Coulomb blockade and the kondo effect. Analysis show that the resultant conductance was in qualitative agreement with experimental data.
