  • Asymptotic scattering and duality in the one-dimensional three-state quantum Potts model on a lattice 
    Rapp, Akos; Schmitteckert, Peter; Takacs, Gabor; Zarand, Gergely (Bristol : IOP Publishing Ltd., 2013-01-28)
    We determine numerically the single-particle and the two-particle spectrum of the three-state quantum Potts model on a lattice by using the density matrix renormalization group method, and extract information on the ...
  • Inversion identities for inhomogeneous face models 
    Frahm, Holger; Karaiskos, Nikos (Amsterdam : Elsevier Science BV, 2014)
    We derive exact inversion identities satisfied by the transfer matrix of inhomogeneous interaction-round-a-face (IRF) models with arbitrary boundary conditions using the underlying integrable structure and crossing properties ...
  • 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 ...
