Spin-ordering and magnon collective modes for two-dimensional electron lattices in strong magnetic fields
Rene Cote,Allan H. MacDonald +1 more
TL;DR: The spin-ordering and the magnon collective modes of the two-dimensional Wigner crystal state at strong magnetic fields are studied and the ground state is ferromagnetic, i.e that all spins are aligned at T=0 even when the electronic g-factor is negligibly small.

Highelandau levels and electron correlation
TL;DR: Exact diagonalization of the Hamiltonian is employed to study the ground state of double-layer system in which a higher Landau level in one layer is degenerate with the ground Landau levels in the other as mentioned in this paper.

TL;DR: In this paper, the authors proposed a new field effect transistors (FETs) based on carbon sheets (graphene) for analog device applications such as low-noise amplifiers and radio frequency (RF)/millimeter-wave field-effect transistors.

Electron-electron interactions in graphene bilayers
TL;DR: In this article, the authors discuss electronelectron interactions in 2D graphene bilayer systems which behave in many ways as if they were one-dimensional, because they have Fermi points instead of fermi lines and their particle-hole energies have a quadratic dispersion which compensates for the difference between 1D and 2D phase space.
