Phonons as collective modes : the case of a two-dimensional Wigner crystal in a strong magnetic field
Rene Cote,Allan H. MacDonald +1 more
TL;DR: A fully quantum-mechanical theory for the phonon modes of a two-dimensional Wigner crystal in the strong-magnetic-field limit is presented, based on a time-dependent Hartree-Fock approximation for the density-density response function χ.
Magnetoplasmons and cyclotron resonance in disordered two-dimensional electronic systems.
TL;DR: This work is based on some new exact sum rules for the inter-Landau-level response functions of noninteracting electrons in a strong magnetic field and in part on perturbative approximations for interaction and disorder.
Functional Keldysh theory of spin torques
TL;DR: In this article, the authors present a microscopic treatment of current-induced torques and thermal fluctuations in itinerant ferromagnets based on a functional formulation of the Keldysh formalism.
Exactly soluble model of fractional statistics.
TL;DR: The present model is inspired by recent applications of supersymmetry and the Atiyah-Singer in- dex theorem to particles in an arbitrary magnetic field and differs in one (highly) nontrivial way from the usual one in that the particles have an attractive hard-core interaction.
