On the integrable structure of the Ising model

Abstract: Starting from the lattice A 3 realization of the Ising model defined on a strip with integrable boundary conditions, the exact spectrum (including excited states) of all the local integrals of motion is derived in the continuum limit by means of TBA techniques. It is also possible to follow the massive flow of this spectrum between the UV c = 1/2 conformal fixed point and the massive IR theory. The UV expression of the eigenstates of such integrals of motion in terms of Virasoro modes is found to have only rat… Show more

“…In this section we are going to derive the exact expressions for the eigenvalues of the lattice Integrals of Motion and after this we will discuss how these eigenvalues are related to the eigenvalues of the conntinuum Integrals of Motion which have been already obtained by means of Themodynamic Bethe Ansatz (TBA) in [5], following lines advocated in [2]. In this case however no TBA will be employed, rather the eigenvalues will be recognized in an expansion that has been already carried out for Critical Dense Polymers in [6] by means of all order Euler-Maclaurin expansion of the factorized form of the eigenvalues.…”

“…In 2 previous papers on the Ising model by the author [3] [4], the integrals of motion (IOM) of Bhazanov Lukyanov and Zamoldchikov (BLZ) [1] were analized by means of Themodynamic Bethe ansatz, and in the most recent work the model on a chain with spatially periodic boundary conditions was analyzed by introducing a finitized version of the BLZ integrals of motion, taking values in the enveloping algebra of the periodic Temperley Lieb algebra with periodic boundaries. In this work it was recognized that the eigenvalues for this finitized IOM admit expansions in 1/N (where N is the size of the system) whose coefficients are related to the continuum eigenvalues of the BLZ IOM.…”

“…In contrast with unitary minimal models, which are realized on the lattice for example by the RSOS models [19] [20] [21], the transfer matrix may exhibit a Jordan indecomposable structure for some choice of Cardy-type boundary conditions. It is well known [5] [6] that the CFT corresponding to critical dense polymers has central charge c = −2.…”
