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…
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…
Detecting quantum critical points at finite temperature via quantum teleportation
G. A. P. Ribeiro, Gustavo Rigolin
We show that the quantum teleportation protocol is a powerful tool to study quantum phase transitions (QPTs) at finite temperatures. We consider a pair of spins from an infinite sp…
On the partition function of the integrable vertex model
G. A. P. Ribeiro
We study the partition function per site of the integrable vertex model on the square lattice. We establish a set of transfer matrix fusion relations for this model. The s…
On the partition function of the integrable vertex model
G. A. P. Ribeiro, A. Klümper, P. A. Pearce
In this paper we investigate certain fusion relations associated to an integrable vertex model on the square lattice which is invariant under symmetry. We establish a set o…
