“Jammed Hard-Sphere Hcp Crystals Permeated With Trivacancy Tunnels” is published in Journal of Applied Physics. Categories News Author chmadmin Read the full paper: here Link to the Journal page: here Supported by simple table-top experiments involving stackings of ball bearings and theoretical analysis, we have discovered crystal packings of identical hard spheres that are permeated by a high concentration of large tunnels and yet are jammed (mechanically stable). We show that starting with a … Continue Reading “Jammed Hard-Sphere Hcp Crystals Permeated With Trivacancy Tunnels” is published in Journal of Applied Physics.

“Phoamtonic Designs Yield Sizeable 3D Photonic Band Gaps” is published in Proceedings of the National Academy of Sciences. Categories News Author chmadmin Read the full paper: here Link to the journal page: here Foams appear ubiquitously in many fields of science and technology. However, applications to photonics have not been possible because until now, foam-based 3D heterostructures with substantial complete photonic band gaps have not been identified. Here we provide explicit examples based on the edges of … Continue Reading “Phoamtonic Designs Yield Sizeable 3D Photonic Band Gaps” is published in Proceedings of the National Academy of Sciences.
