                         via numerical simulations of a coarse-grained model focusing on 
                         the motion of domain walls rather than individual atoms. Following 
                         an initial step profile created in the incommensurate striped 
                         phase, an intermediate hexagonal incommensurate phase nucleates 
                         and grows, leading to a bifurcation into two sharp profiles 
                         propagating in opposite directions as opposed to broad profiles 
                         induced by atomic diffusive motion. Our results are in agreement
