We consider 2D localized rotating patterns which solve a parabolic system of PDEs on the spatial domain R². Under suitable assumptions, we prove nonlinear stability with asymptotic phase with respect to the norm in the Sobolev space H². The stability result is obtained by a combination of energy and resolvent estimates, after the dynamics is decomposed into an evolution within a three–dimensional group orbit and a transversal evolution towards the group orbit.

The stability theorem is applied to the quintic–cubic Ginzburg–Landau equation and illustrated by numerical computations.
