Quasi-particles in the Chiral Potts model
نویسندگان
چکیده
We study the quasi-particle spectrum of the integrable three-state chiral Potts chain in the massive phase by combining a numerical study of the zeroes of associated transfer matrix eigenvalues with the exact results of the ferromagnetic three-state Potts chain and the three-state superintegrable chiral Potts model. We find that the spectrum is described in terms of quasi-particles with momenta restricted only to segments of the Brillouin zone 0 ≤ P ≤ 2π where the boundaries of the segments depend on the chiral angles of the model. 5/94 1 [email protected] 2 [email protected]

Physics beyond quasi - particles : Spectrum and completeness of the 3 state superintegrable chiral Potts model
We find the rules which count the energy levels of the 3 state superintegrable chiral Potts model and demonstrate that these rules are complete. We then derive the complete spectrum of excitations in the thermodynamic limit in the massive phase and demonstrate the existence of excitations which do not have a quasi-particle form. The physics of these excitations is compared with the BCS supercon...
متن کامل3-Chiral Potts Quantum Spin Chain
We study the excitation spectrum and the correlation functions of the Z3-chiral Potts model in the massive high-temperature phase using perturbation expansions and numerical diagonalization. We are mainly interested in results for general chiral angles but we consider also the superintegrable case. For the parameter values considered, we find that the band structure of the low-lying part of the...
متن کاملA Perturbative Approach to Spectrum and Correlation Functions of the Chiral Potts Model
The massive high-temperature phase of the chiral Potts quantum chain is studied using perturbative methods. For the Z 3-chain we present high-temperature expansions for the groundstate energy and the dispersion relations of the two single-particle states as well as two-particle states at general values of the parameters. We also present a perturbative argument showing that a large class of mass...
متن کاملFinite-size Transfer Matrix of Chiral Potts Model with Alternating Rapidities
We establish the Bethe equation of the τ -model in the N -state chiral Potts model (including the degenerate selfdual cases) with alternating vertical rapidities. The eigenvalues of a finite-size transfer matrix of the chiral Potts model are computed by use of functional relations. The significance of the ”alternating superintegrable” case of the chiral Potts model is discussed, and the degener...
متن کاملMulti-particle structure in the ZZn-chiral Potts models
We calculate the lowest translationally invariant levels of the ZZ3and ZZ4symmetrical chiral Potts quantum chains, using numerical diagonalization of the hamiltonian for N ≤ 12 and N ≤ 10 sites, respectively, and extrapolating N → ∞. In the high-temperature massive phase we find that the pattern of the low-lying zero momentum levels can be explained assuming the existence of n− 1 particles carr...
