A 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 کاملCorrelation Functions and Corner Transfer Matrix of the Chiral Potts Model
We use the Density Matrix Renormalization Group technique to compute correlation functions of the Z3-chiral Potts quantum chain in the massive regimes. Chains of up to 70 sites are used and a clear oscillatory behavior is found. We also check the relation between the density matrix spectrum and the Corner Transfer Matrix spectrum pointed out by Nishino and Okunishi, using Baxter’s low-temperatu...
متن کاملChiral-odd distribution functions in the chiral quark soliton model
The recent measurements of azimuthal single spin asymmetries by the HERMES collaboration has opened up new possibility to measure chiral-odd distribution functions through semi-inclusive deep-inelastic scatterings. Here, predictions are given for the twist-2 and twist3 chiral-odd distribution functions of the nucleon within the framework of the chiral quark soliton model, with full inclusion of...
متن کاملCorrelation functions in the Nagel–Schreckenberg model
We investigate the effect of the jamming transition on short-range correlation functions in the Nagel–Schreckenberg cellular automaton model of single-lane traffic. At high densities the structure of the time-dependent correlation functions is double peaked. One peak corresponds to moving cars, the other to blocked cars. The emergence of the latter peak as well as the occurrence of short-range ...
متن کامل1 99 3 Universität Bonn Physikalisches Institut Low - Temperature Expansions and Correlation Functions of the ZZ 3 - Chiral Potts Model
Using perturbative methods we derive new results for the spectrum and correlation functions of the general Z Z 3-chiral Potts quantum chain in the massive low-temperature phase. Explicit calculations of the ground state energy and the first excitations in the zero momentum sector give excellent approximations and confirm the general statement that the spectrum in the low-temperature phase of ge...
