    • Microscopic model for the magnetic subsystem in HoNi2B2C 
      Kalatsky, VA; Pokrovsky, Valery L. (American Physical Society, 1998)
      We demonstrate that the system of localized magnetic moments in HoNi2B2C can be described by the four-positional clock model. This model, at a proper choice of the coupling constants, yields several metamagnetic phases in ...
    • 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 ...
    • Spin glass behavior in FeAl2 
      Lue, CS; Oner, Y.; Naugle, Donald G.; Ross, JH. (American Physical Society, 2001)
      Magnetic and transport measurements indicate FeAl2 to be an ordered intermetallic spin glass, with canonical behavior including a susceptibility cusp at T-f = 35 K and frequency-dependent susceptibility below T-f. The ...
    • Topological color codes on Union Jack lattices: a stable implementation of the whole Clifford group 
      Katzgraber, Helmut G.; Bombin, H.; Andrist, Ruben S.; Martin-Delgado, M. A. (American Physical Society, 2010)
      We study the error threshold of topological color codes on Union Jack lattices that allow for the full implementation of the whole Clifford group of quantum gates. After mapping the error-correction process onto a statistical ...
