Fractional quantum Hall effects as an example of fractal geometry in nature
A prescription is provided for constructing the Hall curve including both integral (I)- and fractional (F)-quantum Hall effects (QHE) that is based upon the iterative application of particular transformations ...

Realization of dual, tunable, ordinary- and quantized-Hall resistances in doubly connected GaAs/AlGaAs heterostructures
An experimental configuration based on gated, double boundary GaAs/AlGaAs devices provides the first demonstration of dual distinct, tunable Hall resistances in the same sample over the weak- and strongmagneti...
