Topological growth control allows to produce a narrow distribution of outgrown colloidal rods with defined and adjustable length. We use an external magnetic field assemble paramagnetic spheres into chosen The reside above ametamorphic hexagonalmagnetic pattern. periodic repetition specific loops the orientation applied renders particles their assemblies active bipeds that walk on metamorphic patterns allow robust controlled polymerization single colloids desired are exposed this fixed loop...
Topological protection ensures stability of information and particle transport against perturbations. We explore experimentally computationally the topologically protected magnetic colloids above spatially inhomogeneous patterns, revealing that complexity can be encoded in both driving loop pattern. Complex patterns support intricate modes when microparticles are subjected to simple time-periodic loops a uniform field. design pattern featuring topological defect functions as an attractor or...
We measure the dynamical behavior of colloidal singlets and dumbbells on an inclined magnetic moiré pattern, subject to a precessing external homogeneous field. At low field strength single particles move everywhere pattern: at stronger strengths are localized in generic locations. There however nongeneric locations flat channels that cross Wigner Seitz cell. In we find gravitational driven translational non-translational dynamic phase depending precession angle
