New Q matrices and their functional equations for the eight vertex model at elliptic roots of unity
نویسندگان
چکیده
The Q matrix invented by Baxter in 1972 to solve the eight vertex model at roots of unity exists for all values of N , the number of sites in the chain, but only for a subset of roots of unity. We show in this paper that a new Q matrix, which has recently been introduced and is non zero only for N even, exists for all roots of unity. In addition we consider the relations between all of the known Q matrices of the eight vertex model and conjecture functional equations for them.

Functional Equations and Fusion Matrices for the Eight Vertex Model
We derive sets of functional equations for the eight vertex model by exploiting an analogy with the functional equations of the chiral Potts model. From these equations we show that the fusion matrices have special reductions at certain roots of unity. We explicitly exhibit these reductions for the 3,4 and 5 order fusion matrices and compare our formulation with the algebra of Sklyanin.

We demonstrate that the τ (j)-matrices in the superintegrable chiral Potts model possess the Onsager algebra symmetry for their degenerate eigenvalues. The Fabricius-McCoy comparison of functional relations of eight-vertex model for roots of unity and superintegrable chiral Potts model has been carefully analyzed by identifying equivalent terms in the corresponding equations , by which we extra...

متن کاملAuxiliary matrices on both sides of the equator
The spectra of previously constructed auxiliary matrices for the six-vertex model at roots of unity are investigated for spin-chains of even and odd length. The two cases show remarkable differences. In particular, it is shown that for even roots of unity and an odd number of sites the eigenvalues contain two linear independent solutions to Baxter’s TQ-equation corresponding to the Bethe ansatz...
متن کاملA new Q-matrix in the Eight-Vertex Model
We construct a Q-matrix for the eight-vertex model at roots of unity for crossing parameter η = 2mK/L with odd L, a case for which the existing constructions do not work. The new Q-matrix Q̂ depends on the spectral parameter v and also on a free parameter t. For t = 0 Q̂ has the standard properties. For t 6= 0, however, it does not commute with the operator S and not with itself for different val...
