• Disclination unbinding transition in quantum Hall liquid crystals 

    Dorsey, Alan T.; Wexler, Carlos, 1966- (American Physical Society, 2001-08)
    We derive the long-wavelength elastic theory for the quantum Hall smectic state starting from the Hartree-Fock approximation. Dislocations in this state lead to an effective nematic model for T>0, which undergoes a ...
  • Spin-Hall effect and spin-Coulomb drag in doped semiconductors 

    Hankiewicz, E. M.; Vignale, Giovanni, 1957- (American Institute of Physics, 2009-05)
    In this review, we describe in detail two important spin-transport phenomena: the extrinsic spin-Hall effect (coming from spin-orbit interactions between electrons and impurities) and the spin-Coulomb drag. The interplay ...
