“More is different”: Nanofabricated chiro-optical material based on 8-fold intergrowth of gyroid


In a totally different context to the original quote and article, Phil Anderson’s quote “More is different” holds also for the chiro-optical response of gyroid-based photonic materials. Eight intergrown Gyroids give a substantially different chiro-optical response than the single gyroid. The group theoretic prediction from Matthias Saba’s PhD work (Saba et al, PRB 2013) has now been experimentally validated by Nanofabrication experiments in the Center for Microphotonics at Swinburne University (Turella et al, Optics Letters, 2015).

In a Material World


“In a Material World: Hyperbolic Geometry in Biological Materials”, by Myf Evans and myself, is a popular-science type essay on the sort of geometric questions that we see of relevance for soft matter physics, materials science, biology, etc. In particular, what’s the role of hyperbolic geometry and triply-periodic minimal surfaces, and what’s the geometric rationale why they form in soft matter self-assembly. Hopefully an entertaining read, with no claim to be comprehensive, and certainly not original research. Read more
