Abstract

We extend our studies of the TQ equation introduced by Baxter in his 1972 solution of the eight-vertex model with parameter η given by 2 L η = 2 m 1 K + i m 2 K ' from m 2 = 0 to the more general case of complex η. We find that there are several different cases depending on the parity of m 1 and m 2 .

Solving Baxter's TQ-equation via representation theory

Christian Korff

Baxter's TQ-equation is solved for the six-vertex model using the representation theory of quantum groups at roots of unity. A novel simplified construction of the Q-operator is given depending on a new free parameter. Specializing this general construction to even roots of unity and lattices with an odd number of columns two linearly independent operator solutions of Baxter's TQ equation are obtained as special limits.

Representation Theory and Baxter's TQ equation for the six-vertex model. A pedagogical overview

Christian Korff

A summary of the construction procedure of generalized versions of Baxter's Q-operator is given. Illustrated by several figures and diagrams the use of representation theory is explained step-by-step avoiding technical details. The relation with the infinite-dimensional non-abelian symmetries of the six-vertex model at roots of unity is discussed and parallels with the eight-vertex case outlined.

A newQ-matrix in the eight-vertex model

K. Fabricius

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 $\Q$ depends as usual on the spectral parameter and also on a free parameter $t$. For $t=0$ $\Q$ has the standard properties. For $t\neq 0$, however, it does not commute with the operator $S$ and not with itself for different values of the spectral parameter. We show that the six-vertex limit of $\Q(v,t=iK'/2)$ exists.

New developments in the eight-vertex model II. Chains of odd length

K. Fabricius, Barry M. McCoy

We study the transfer matrix of the 8 vertex model with an odd number of lattice sites N. For systems at the root of unity points η = mK/L with m odd the transfer matrix is known to satisfy the famous “TQ ” equation where Q(v) is a specifically known matrix. We demonstrate that the location of the zeroes of this Q(v) matrix is qualitatively different from the case of even N and in particular they satisfy a previously unknown equation which is more general than what is often called “Bethe’s equation. ” For the case of even m where no Q(v) matrix is known we demonstrate that there are many states which are not obtained from the formalism of the SOS model but which do satisfy the TQ equation. The ground state for the particular case of η = 2K/3 and N odd is investigated in detail.

We construct a QQQ-matrix for the eight-vertex model at roots of unity for crossing parameter η=2mK/Lη=2mK/Lη=2mK/L with odd LLL, a case for which the existing constructions do not work. The new QQQ-matrix $\Q$ depends as usual on the spectral parameter and also on a free parameter ttt. For t=0t=0t=0 $\Q$ has the standard properties. For t≠0t\neq 0t=0, however, it does not commute with the operator SSS and not with itself for different values of the spectral parameter. We show that the six-vertex limit of $\Q(v,t=iK'/2)$ exists.
