## Abstract

The effect of shear on the ordering-kinetics of a conserved order-parameter system with O(n) symmetry and order-parameter-dependent mobility \\Gamma({\\vec\\phi}) \\propto (1- {\\vec\\phi} ^2/n)^\\alpha is studied analytically within the large-n limit. In the late stage, the structure factor becomes anisotropic and exhibits multiscaling behavior with characteristic length scales (t^{2\\alpha+5}/\\ln t)^{1/2(\\alpha+2)} in the flow direction and (t/\\ln t)^{1/2(\\alpha+2)} in directions perpendicular to the flow. As in the \\alpha=0 case, the structure factor in the shear-flow plane has two parallel ridges.

## Recorded benchmark results

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.
