Correlations in Ising chains with nonintegrable interactions.
Two-spin correlations generated by interactions which decay with distance r as r−1−σ with −1 < σ < 0 are calculated for periodic Ising chains of length L. Mean-field theory indicates that the correlations, C(r, L), diminish in the thermodynamic limit L → ∞, but they contain a singular structure for r/L → 0 which can be observed by introducing magnified correlations, LC(r, L)−∑r C(r, L). The mag...
متن کاملShort Distance Asymptotics of Ising Correlations
We prove that the short distance asymptotics for the even Ising model scaling functions from below Tc is given by the Luther-Peschel formula. Generalizations to the odd scaling functions and Holonomic Fields are given.
متن کاملCorrelations and fractality in random Ising magnets
We investigate the behavior of domains in random Ising magnets by a Monte Carlo simulation. We calculate the spatial correlation function of the frozen domain state of twoand three-dimensional diluted antiferromagnets in an external magnetic field and compare the results with those line shapes found from neutron scattering experiments. An analysis leads to a new interpretation of the correspond...
متن کاملPeriodic-orbit theory of level correlations.
We present a semiclassical explanation of the so-called Bohigas-Giannoni-Schmit conjecture which asserts universality of spectral fluctuations in chaotic dynamics. We work with a generating function whose semiclassical limit is determined by quadruplets of sets of periodic orbits. The asymptotic expansions of both the nonoscillatory and the oscillatory part of the universal spectral correlator ...
متن کاملIsing-model description of long-range correlations in DNA sequences.
We model long-range correlations of nucleotides in the human DNA sequence using the long-range one-dimensional (1D) Ising model. We show that, for distances between 10(3) and 10(6) bp, the correlations show a universal behavior and may be described by the non-mean-field limit of the long-range 1D Ising model. This allows us to make some testable hypothesis on the nature of the interaction betwe...
