Crystalline Particle Packings on a Sphere with Long Range Power Law Potentials
Mark J. Bowick, Angelo Cacciuto, David R. Nelson +1
The original Thomson problem of "spherical crystallography" seeks the ground state of electron shells interacting via the Coulomb potential; however one can also study crystalline…
Direct Visualization of Dislocation Dynamics in Grain Boundary Scars
Peter Lipowsky, Mark J. Bowick, Jan H. Meinke +2
Mesoscale objects with unusual structural features may serve as the analogues of atoms in the design of larger-scale materials with novel optical, electronic or mechanical behaviou…
Grain Boundary Scars on Spherical Crystals
Thomas Einert, Peter Lipowsky, Jorg Schilling +2
We present an experimental system suitable for producing spherical crystals and for observing the distribution of lattice defects (disclinations and dislocations) on a significant…
