Multi-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...
متن کاملThe challenge of the chiral Potts model
The chiral Potts model continues to pose particular challenges in statistical mechanics: it is “exactly solvable” in the sense that it satisfies the Yang-Baxter relation, but actually obtaining the solution is not easy. Its free energy was calculated in 1988 and the order parameter was conjectured in full generality a year later. However, a derivation of that conjecture had to wait until 2005. ...
متن کاملQuasi-particles in the Chiral Potts model
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...
متن کاملThe forgotten Potts models
The q = 10 and q = 200 state Potts models coupled to 2d gravity are investigated numerically and shown to have continuous phase transitions, contrary to their behavior on a regular lattice. Critical exponents are extracted and possible critical behavior for general q-state Potts models coupled to gravity is discussed.
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...
