    • Hall effect at a tunable metal-insulator transition 

      Teizer, Winfried; Hellman, F.; Dynes, RC. (American Physical Society, 2003)
      Using a rotating magnetic field, the Hall effect in three-dimensional amorphous GdxSi1-x has been measured in the critical regime of the metal-insulator transition for a constant total magnetic field. The Hall coefficient ...
    • Numerical studies of a one-dimensional three-spin spin-glass model with long-range interactions 

      Larson, Derek; Katzgraber, Helmut G.; Moore, M. A.; Young, A. P. (American Physical Society, 2010)
      We study a p-spin spin-glass model to understand if the finite-temperature glass transition found in the mean-field regime of p-spin models, and used to model the behavior of structural glasses, persists in the nonmean-field ...
    • Weakly interacting Bose gas in a random environment 

      Falco, G. M.; Nattermann, T.; Pokrovsky, Valery L. (American Physical Society, 2009)
      The localization-disorder paradigm is analyzed for a specific system of weakly repulsive Bose gas at zero temperature placed into a quenched random potential. We show that at low average density or weak enough interaction ...
