TL;DR: In this paper, the electron addition spectra of quantum dots in a broad range of electron occupancies starting from the first electron were studied and it was shown that electron additions are not evenly spaced in gate voltage rather, they group into bunches.

TL;DR: Measurements revealing anomalously large frictional drag at the transition between the weakly and strongly coupled regimes of a bilayer two-dimensional electron system at total Landau level filling factor nu(T)=1 suggest the existence of fluctuations near the phase boundary separating the quantized Hall state at small layer separations from the compressible state at larger separations.

TL;DR: In this article, the many-body wave function of localized states in one dimension is probed by measuring the tunneling conductance between two parallel wires, fabricated in a geometrical heterostructure.

TL;DR: In this paper, swept area interference measurements at 5/2 were performed, and the authors observed an alternating pattern of e/4 and e/2 period oscillations in resistance.

TL;DR: In this paper, the longitudinal resistivity of two-dimensional electrons near half filling of high Landau levels is found to persist to much higher temperatures T when a large in-plane magnetic field B is applied.
