A condensed matter physicist who coauthored a charging model for tunneling through antidot states in the quantum Hall effect. Compressible rings associated with two spin branches can make an outer-edge resonance recur twice per usual flux period of the Aharonov-Bohm effect. This connects an apparently anomalous period to Coulomb blockade and charge rearrangement rather than a change in elementary electric charge.[ref]
Coulomb blockade of tunnelling through compressible rings formed around an antidot by M. Kataoka and others. Abstract: compressible rings and two resonances per h/e cycle
