Summary:

We consider a model of nonequilibrium pattern formation. Probes on a ring are in contact with a driven diffusive dynamics and, close to the equidistant probe configuration, the induced forces generate a linear dynamics with nonsymmetric coupling constants. A compound Poisson process describes the nonvariational relaxation to that crystal pattern.
