摘要: There are many examples of interacting particles that have both repulsive and attractive interaction terms. Assemblies such can form clumps, gel type states, labyrinths other patterns, while two-dimensional systems with purely interactions typically hexagonal crystals. Here we examine the pattern formation colloids competing in presence a quasi-one dimensional periodic substrate. For soft matter systems, substrates be created by various optical means. We show substrate induce patterns including commensurate bubble phases as well modulated stripes aligned Beyond colloids, these results should also general to modeled moving over surface or modulation.
