| 1032 | Controlling Topological Defects in Colloidal Crystal Shells of Hard Superballs Related Papers Related Patents Related Grants Related Venues Related Experts View Highlight: Here we use hard particle Monte Carlo simulations to determine the effect of particle shape and lattice preference in flat space on the structure and distribution of defects in spherical shells filled densely with colloidal particles whose shape varies continuously from a sphere to a cube. We describe defect scar analogues for these systems and show how the scar pattern relates to particle shape. |

| 1034 | Using Potentials to Model The Crystallography of Bee Honeycomb Under Geometric Frustration Related Papers Related Patents Related Grants Related Venues Related Experts View Highlight: When faced with various geometric constraints, such as boundaries or connecting combs with different orientations, the resulting comb is irregular, with several topological defects. In this work, we study this process using 3D-print experimental frames with imprinted foundations, which impose a precise geometric frustration. |

Here, we introduce a general method combining parametric pumping and quenching to non-invasively control the configuration of such a multi-particle system and demonstrate it with an acoustically levitated small cluster of particles. |
