  • Finite-size effects in the spectrum of the OSp(3|2) superspin chain 
    Frahm, Holger; Martins, Márcio J. (Amsterdam : Elsevier Science BV, 2015)
    The low energy spectrum of a spin chain with OSp(3|2)supergroup symmetry is studied based on the Bethe ansatz solution of the related vertex model. This model is a lattice realization of intersecting loops in two dimensions ...
  • Integrable anyon chains: From fusion rules to face models to effective field theories 
    Finch, Peter E.; Flohr, Michael; Frahm, Holger (Amsterdam : Elsevier Science BV, 2014)
    Starting from the fusion rules for the algebra SO(5)2we construct one-dimensional lattice models of interacting anyons with commuting transfer matrices of ‘interactions round the face’ (IRF) type. The con-served topological ...
  • Transmission amplitudes from Bethe ansatz equations 
    Doikou, Anastasia; Karaiskos, Nikos (New York, NY : Springer International Publishing, 2013)
    We consider the Heisenberg spin chain in the presence of integrable spin defects. Using the Bethe ansatz methodology, we extract the associated transmission amplitudes, that describe the interaction between the particle-like ...
