Abstract

The interaction of edge states via localized states leads to the ``generic'' breakdown of the quantum Hall effect. Using a versatile two-antidot structure we study the magnetoconductance oscillations of coupled antidot systems in regimes where ``atomic'' modes exist around individual antidots in addition to ``molecular'' modes encompassing both antidots. We find and discuss an apparent passivity of the molecular modes during both resonant transmission and reflection processes.
