The XXC Models
نویسنده
چکیده
A class of recently introduced multi-states XX models is generalized to include a deformation parameter. This corresponds to an additional nearest-neighbor CC interaction in the defining quadratic hamiltonian. Complete integrability of the one-dimensional models is shown in the context of the quantum inverse scattering method. The new R-matrix is derived. The diagonalization of the XXC models is carried out using the algebraic Bethe Ansatz.

Comments on New representations of the Hecke algebra and algebraic Bethe Ansatz for an integrable generalized spin ladder, Abstract The authors of cond-mat/9911072 claim to introduce " new representations of the Hecke algebra. " These representations are shown to be the XXC models introduced two years ago in solv-int/9712008, and repeatedly studied and referred to in subsequent papers. They are...
متن کاملMultiplicity Am Models
Models generalizing the su(2) XX spin-chain were recently introduced. These XXC models also have an underlying su(2) structure. Their construction method is shown to generalize to the chains based on the fundamental representations of the Am Lie algebras. Integrability of the new models is shown in the context of the quantum inverse scattering method. Their R-matrix is found and shown to yield ...
متن کاملFermionization and Hubbard Models
We introduce a transformation which allows the fermionization of operators of any onedimensional spin-chain. This fermionization procedure is independent of any eventual integrable structure and is compatible with it. We illustrate this method on various integrable and non-integrable chains, and deduce some general results. In particular, we fermionize XXC spin-chains and study their symmetries...
متن کاملOn the Speed of Convergence of Iteration of a Function
Let fn(X) be the nth iterate of a function in some interval [0, c]. It is known that if f(x) xxc, a > 1, then fn(X) An for some A and a. In this paper we prove a converse of this theorem: The rate of convergence of the iterates determines the form of a function.
متن کاملBiotin binders selected from a random peptide library expressed on phage.
Recombinant biotin-binding phages were affinity-selected from a random peptide library expressed on the surface of filamentous phage. Phage binding to biotinylated proteins was half-maximally inhibited by micromolar concentrations of a monobiotinylated molecule. Sequencing of the peptide inserts of selected phages led to the identification of a previously unknown biotin-binding motif, CXWXPPF(K...
