  • Spin chains and vertex models based on superalgebras 
    Hobuß, Konstantin (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2019)
    The thermodynamic limit of superspin chains can show several intriguing properties, including the emergence of continua of scaling dimensions and the appearance of discrete states when imposing toroidal boundary conditions. ...
  • The staggered six-vertex model: Conformal invariance and corrections to scaling 
    Frahm, Holger; Seel, Alexander (Amsterdam : Elsevier Science BV, 2014)
    We study the emergence of non-compact degrees of freedom in the low energy effective theory for a class of Z2Z2-staggered six-vertex models. In the finite size spectrum of the vertex model this shows up through the appearance ...
