Abstract
The critical dynamics of a model isotropic antiferromagnet is studied in dimensions above and at . The renormalization-group, characteristic-frequency exponent, and shape function are determined to order . In particular we find fluctuation-induced peaks in the shape function at and above the Néel temperature. We find results in agreement with dynamical scaling.
