Surface Critical Properties in Nonlinear σ Model

K. Nojima

Published Oct 15, 1991• 0 citations
Publisher

Abstract

By extending the nonlinear sigma model to the semi-infinite geometry, the correlation function exponents η // , η ⊥ of the ordinary transition are estimated to the order of ε 2 (ε= d -2).

Jeff S. Reeve, Anthony John Guttmann

The surface and local susceptibility exponents gamma 1 and gamma 11 for semi-infinite phi 4 , O(n) systems are calculated to order epsilon =4-d at the ordinary bulk transition temperature. The results agree with the predictions of correlation function scaling.

Renormalisation group calculations of the critical exponents of the n-vector model with a free surface

J Reeve, Anthony John Guttmann

The correlation function critical exponents eta /sub /// and eta perpendicular to of the semi-infinite phi 4 model with O(n) symmetry have been calculated to order epsilon 2 for the ordinary and special transitions. The results for the ordinary transition are inconsistent with the relation gamma 11 = nu -1 proposed by Bray and Moore (1977). Comparisons with series expansion results in two and three dimensions are presented for n=0 and n=1.

Critical behavior of the nonlinearσmodel with a free surface: The ‘‘ordinary’’ transition in 2+ε dimensions

Hans Werner Diehl, Adi Nusser

We analyze the critical behavior of isotropic ferromagnets with a free surface by means of field-theoretic renormalization methods in d=2+\ensuremath{\epsilon} dimensions. Renormalization-group equations for surface quantities are derived which imply scaling to all orders in \ensuremath{\epsilon}. Explicit results to order ${\mathrm{\ensuremath{\epsilon}}}^{2}$ are presented for the critical surface exponents of the ordinary transition. Interpolation with the known results near four dimensions yields estimates for d=3 which seem to be remarkably accurate.
