AbstractThe 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.
