  • Integrable boundary conditions for staggered vertex models 
    Frahm, Holger; Gehrmann, Sascha (Bristol : IOP Publ., 2023)
    Yang-Baxter integrable vertex models with a generic Z 2 -staggering can be expressed in terms of composite R -matrices given in terms of the elementary R-matrices. Similarly, integrable open boundary conditions can be ...
  • Truncation identities for the small polaron fusion hierarchy 
    Grabinski, Andre M.; Frahm, Holger (Bristol : IOP Publishing Ltd., 2013-04-17)
    We study a one-dimensional lattice model of interacting spinless fermions. This model is integrable for both periodic and open boundary conditions; the latter case includes the presence of Grassmann valued non-diagonal ...
