Form-factors in the Baxter-Bazhanov-Stroganov model II: Ising model on the finite lattice
G. von Gehlen, N. Iorgov, S. Pakuliak +2
We continue our investigation of the Baxter-Bazhanov-Stroganov or τ^{(2)}-model using the method of separation of variables [nlin/0603028,arXiv:0708.4342]. In this paper we derive…
Form-factors in the Baxter-Bazhanov-Stroganov model I: Norms and matrix elements
G. von Gehlen, N. Iorgov, S. Pakuliak +2
We continue our investigation of the Z_N-Baxter-Bazhanov-Stroganov model using the method of separation of variables [nlin/0603028]. In this paper we calculate the norms and matrix…
Finite-size energy levels of the superintegrable chiral Potts model
G. von Gehlen
In the solution of the superintegrable chiral Potts model special polynomials related to the representation theory of the Onsager algebra play a central role. We derive approximate…
Phase diagram and two-particle structure of the -chiral Potts model
G. von Gehlen
We calculate the low-lying part of the spectrum of the -symmetrical chiral Potts quantum chain in its self-dual and integrable versions, using numerical diagonalisation of the…
