    Generalized Exclusion Statistics in the Kondo Problem

    Full text link
    We consider the generalized exclusion statistics in the Kondo problem. The thermodynamic Bethe ansatz equations have been used for a multicomponent system of particles obeying the generalized exclusion principle. We have found a relation between the derivative of the phase shift of the scattering matrix for Fermi particles and for particles characterized by generalized exclusion statistics. We show that the statistical matrix in the Kondo problem has a universal form in high and low temperature limits.Comment: 15 pages Sabj-class: Strongly Correlated Electron

    Structure of Multi-Meron Knot Action

    Full text link
    We consider the structure of multi-meron knot action in the Yang-Mills theory and in the CP^1 Ginzburg-Landau model. Self-dual equations have been obtained without identifying orientations in the space-time and in the color space. The dependence of the energy bounds on topological parameters of coherent states in planar systems is also discussed. In particular, it is shown that a characteristic size of a knot in the Faddeev-Niemi model is determined by the Hopf invariant.Comment: 7 pages, Latex2

    Nonlocal Edge State Transport in Topological Insulators

    Get PDF
    We use the N-terminal scheme for studying the edge state transportin in two-dimensional topological insulators. We find the universal nonlocal response in the ballistic transport approach. This macroscopic exhibition of the topological order offers different areas for applications.Comment: Updated to published versio

    Topological phase states of the SU(3) QCD

    Physics and Mathematics of Nonlinear Phenomena 2013 (PMNP2013).We consider the topologically nontrivial phase states and the corresponding topological defects in the SU(3) d-dimensional quantum chromodynamics (QCD). The homotopy groups for topological classes of such defects are calculated explicitly. We have shown that the three nontrivial groups are π3SU(3) = Z, π5SU(3) = Z, and π6SU(3) = Z6 if 3 ≤ d ≤ 6. The latter result means that we are dealing exactly with six topologically different phase states. The topological invariants for d=3,5,6 are described in detail.This work was supported in part by the RFBR Grant No. 13-02-12110.Peer Reviewe
