Renormalization of the Nonlinear σ Model in 2 + ε Dimensions—Application to the Heisenberg Ferromagnets

Brézin, E., Zinn-Justin, J.·1976·Physical Review Letters

Abstract

The nonlinear $\ensuremath{\sigma}$ model is renormalizable and asymptotically free in two dimensions. We show here how to construct this model in $2+\ensuremath{\epsilon}$ dimensions. Renormalization-group equations follow and exhibit a nontrivial uv stable fixed point, which corresponds in the language of Heisenberg ferromagnets to a critical point. The existence of systematic expansions in powers of $d\ensuremath{-}2$ follows from this analysis. In the presence of a source information about long-distance behavior above the critical coupling constant is obtainable.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
