  • 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 ...
  • Field-controlled spin current in frustrated spin chains 
    Kolezhuk, A.K.; McCulloch, I.P. (Condensed Matter Physics, 2009)
    We study states with spontaneous spin current, emerging in frustrated antiferromagnetic spin-S chains subject to a strong external magnetic field. As a numerical tool, we use a non-Abelian symmetry realization of the density ...
