    • Critical behavior and universality in Levy spin glasses 
      Andresen, Juan Carlos; Janzen, Katharina; Katzgraber, Helmut G. (American Physical Society, 2011)
      Using large-scale Monte Carlo simulations that combine parallel tempering with specialized cluster updates, we show that Ising spin glasses with Levy-distributed interactions share the same universality class as Ising spin ...
    • Long-wavelength anomalous diffusion mode in the two-dimensional XY dipole magnet 
      Abanov, Artem; Kashuba, A.; Pokrovsky, Valery L. (American Physical Society, 1997)
      In a two-dimensional XY ferromagnet the dipole force induces a strong interaction between spin waves in the long-wavelength limit. The major effect of this interaction is the transformation of a propagating spin wave into ...
