The phase diagram of an interacting two-dimensional electron system in a high magnetic
field is enriched by the varying form of the effective Coulomb interaction, which depends …

On the basis of energy calculations we investigate the competition between quantum-liquid
and electron-solid phases in the Landau levels n= 1, 2, and 3 as a function of their partial …

We report drastically different onset temperatures of the reentrant integer quantum Hall
states in the second and third Landau level. This finding is in quantitative disagreement with …

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 …

A graphene bilayer in a transverse magnetic field has a set of Landau levels with energies
E=±N (N+ 1) ℏ ω c∗, where ω c∗ is the effective cyclotron frequency and N= 0, 1, 2,… All …

In the higher Landau levels (N> 0) a reentrant integer quantum Hall effect (RIQHE) state,
which resides at fractional filling factors but exhibits integer Hall plateaus, has been …

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

We study the radio-frequency diagonal conductivities of the anisotropic stripe phases of
higher Landau levels near half-integer fillings. In the hard direction, in which larger dc …

We study the ground state of a nematic phase of the two-dimensional electron gas at filling
fraction ν= 1∕ 2 using a variational wave function having Jastrow pair correlations of the …

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 …
