It is widely held that disorder is essential to the existence of a finite interval of magnetic field
in which the Hall conductance is quantized, ie, for the existence of “plateaus” in the quantum …

We focused on the transverse AC magnetoconductance of a high-mobility p-GaAs/AlGaAs
quantum well (p= 1.2× 10 11 cm− 2) in the vicinity of two values of the Landau-level filling …

We report the observation of a resonance in the microwave spectra of the real diagonal
conductivities<? format?> of a two-dimensional electron system within a range of∼±0.015 …

For filling factors ν in the range between 4.16 and 4.28, we simultaneously detect two
resonances in the real diagonal microwave conductivity of a two-dimensional electron …

We have investigated the behavior of electronic phases of the second Landau level under
tilted magnetic fields. The fractional quantum Hall liquids at ν= 2+ 1/5 and 2+ 4/5 and the …

The interplay of strong Coulomb interactions and of topology is currently under intense
scrutiny in various condensed matter and atomic systems. One example of this interplay is …

Stripelike and bubblelike patterns spontaneously form in numerous physical, chemical, and
biological systems when competing long-range and short-range interactions banish …

We report complex magnetotransport patterns of the ν= 1 integer quantum Hall state in a
GaAs/AlGaAs sample from the newest generation with a record high electron mobility. The …

Microwave pinning-mode resonances found around integer quantum Hall effects, are a
signature of crystallized quasiparticles or holes. Application of in-plane magnetic field to …

At low energy, the band structure of graphene can be approximated by two degenerate
valleys (K, K′) about which the electronic spectra of the valence and conduction bands …
