Correlation functions of the 19-vertex IRF model and its integrable quantum spin-1 chain
T. S. Tavares, H. B. Abreu, G. A. P. Ribeiro
We consider the interaction-round-a-face version of the nineteen-vertex model and derive a new quantum spin- chain. In the isotropic limit, the associated spin chain can be seen…
Correlation functions of the six-vertex IRF model and its quantum spin chain
T. S. Tavares, G. A. P. Ribeiro
We consider the interaction-round-a-face version of the isotropic six-vertex model. The associated spin chain is made of two coupled Heisenberg spin chains with different boundary…
Canonical formulation for the thermodynamics of -invariant integrable spin chains
T. S. Tavares, I. R. Passos, A. Klümper
Integrable quantum spin chains display distinctive physical properties making them a laboratory to test and assess different states of matter. The study of the finite temperature p…
Finite temperature properties of an integrable zigzag ladder chain
T. S. Tavares, G. A. P. Ribeiro
We consider the interaction-round-a-face version of the six-vertex model for arbitrary anisotropy parameter, which allow us to derive an integrable one-dimensional quantum Hamilton…
Topological defects in periodic RSOS models and anyonic chains
J. Belletête, A. M. Gainutdinov, J. L. Jacobsen +2
We provide a lattice regularization of all topological defects in minimal models CFTs using RSOS and anyonic spin chains. For defects of type , we connect our result with th…
Topological defects in lattice models and affine Temperley-Lieb algebra
J. Belletête, A. M. Gainutdinov, J. L. Jacobsen +2
This paper is the first in a series where we attempt to define defects in critical lattice models that give rise to conformal field theory topological defects in the continuum limi…
Finite size and finite temperature studies of the spin chain
T. S. Tavares, G. A. P. Ribeiro
We study a quantum spin chain invariant by the superalgebra . We derived non-linear integral equations for the row-to-row transfer matrix eigenvalue in order to analyze i…
Exact thermodynamics and phase diagram of integrable t-J model with chiral interaction
T. S. Tavares, G. A. P. Ribeiro
We study the phase diagram and finite temperature properties of an integrable generalization of the one-dimensional super-symmetric t-J model containing interactions explicitly bre…
Influence of boundary conditions on bulk properties of six-vertex model
T. S. Tavares, G. A. P. Ribeiro, V. E. Korepin
We study the influence of boundary conditions on the entropy of the six-vertex model. We consider the case of fixed boundary conditions in order to argue that the entropy of the si…
Magnetocaloric effect in the spin- chain with competing interactions
T. S. Tavares, G. A. P. Ribeiro
We study the magnetocaloric effect for the integrable antiferromagnetic Heisenberg spin chain with competing interactions. We computed the Grüneisen parameter, which is closely rel…
Thermodynamics of quantum spin chains with competing interactions
T. S. Tavares, G. A. P. Ribeiro
We consider integrable quantum spin chains with competing interactions. We apply the quantum transfer matrix approach to these spin chains. This allowed us to derive a set of non-l…
