Non-Close-Packed Three-Dimensional Quasicrystals
Pablo F. Damasceno, Sharon C. Glotzer, Michael Engel
Quasicrystals are frequently encountered in condensed matter. They are important candidates for equilibrium phases from the atomic scale to the nanoscale. Here, we investigate the…
Self-assembly of a space-tessellating structure in the binary system of hard tetrahedra and octahedra
Andrew T. Cadotte, Julia Dshemuchadse, Pablo F. Damasceno +2
We report the formation of a binary crystal of hard polyhedra due solely to entropic forces. Although the alternating arrangement of octahedra and tetrahedra is a known space-tesse…
The Role of Short-Range Order and Hyperuniformity in the Formation of Band Gaps in Disordered Photonic Materials
Luis S. Froufe-Pérez, Michael Engel, Pablo F. Damasceno +4
We study photonic band gap formation in two-dimensional high refractive index disordered materials where the dielectric structure is derived from packing disks in real and reciproc…
Controlling Chirality of Entropic Crystals
Pablo F. Damasceno, Andrew S. Karas, Benjamin A. Schultz +2
Colloidal crystal structures with complexity and diversity rivaling atomic and molecular crystals have been predicted and obtained for hard particles by entropy maximization. Howev…
