  • Classical and quantum anisotropic Heisenberg antiferromagnets 
    Selke, W.; Bannasch, G.; Holtschneider, M.; McCulloch, I.P.; Peters, D.; Wessel, S. (Condensed Matter Physics, 2009)
    We study classical and quantum Heisenberg antiferromagnets with exchange anisotropy of XXZ-type and crystal field single-ion terms of quadratic and quartic form in a field. The magnets display a variety of phases, including ...
  • Ising antiferromagnet with mobile, pinned, and quenched defects 
    Selke, W.; Holtschneider, M.; Leidl, R. (Condensed Matter Physics, 2005)
    Motivated by recent experiments on (Sr,Ca,La)₁₄Cu₂₄O₄₁, a two-dimensional Ising antiferromagnet with mobile, locally pinned and quenched defects is introduced and analyzed using mainly Monte Carlo techniques. The ...
