Properties of Reentrant Integer Quantum Hall States in High Landau Levels

ORAL

Abstract

Reentrant integer quantum Hall states in two-dimensional electron gases are commonly associated with electronic bubble phases, novel electronic solids predicted by Hartree-Fock theories. Various measurements were all consistent with the Hartree-Fock theory, with the exception of predictions of proliferation of such ground states in high Landau levels. This has recently changed with observations of double reentrance in the N=3 Landau level. We will discuss the filling factor and the temperature dependence of magnetotransport of the reentrant integer quantum Hall states in the N=3 Landau level. Our findings significantly strengthen the bubble interpretation of the reentrant integer quantum Hall states and provide insight into details of the competition of electron-electron interaction and disorder effects in the formation of the electronic bubbles.
