AbstractThe self-assembled domain patterns of modulated systems are the result of competing short-range attractive and long-range repulsive interactionsfound in diverse physical and chemical systems. From an application point of view, there is considerable interest in these domain patterns,as they form templates suitable for the fabrication of nanostructures. In this work we have generated a variety of new and exotic patterns,which represent either metastable or glassy states. These patterns arise as a compromise between the required equilibrium modulation periodand the strain resulting from topologically constrained trajectories in phase space that effectively preclude the equilibrium configuration.
