“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

Conference Geometry and Physics of Random Spatial Structures, Black Forest 7-11 Sept 2015


Held in the picturesque Black Forest region of Germany from 7-11 September 2015, this conference will cover the mathematics and physics of disordered spatial structures and systems. Keynote speakers at this event include: Anton Bovier, Paul Chaikin, Wiebke Drenckhan, Matthew Kahle, Randall Kamien, Domenico Marinucci, Frank den Hollander and Rien van der Weygaert. We’re still accepting poster abstracts for this conference, see www.gpsrs.de

Shape Up 2015 : Exercises in Materials Geometry and Topology


We’re still accepting abstracts for what shapes up to be an exciting international conference  on real-world materials, dead and alive, with complex spatial microstructures. An interdisciplinary discussion meeting on patterns and geometry, and their role in biological and synthetic microstructured materials and tissue. We invite contributions from biology, chemistry, materials science, mathematics, physics and related fields addressing the genesis, properties and function of complex nano-scale geometries, as well as underlying geometric and topological concepts for the study of complex structure and shape. More information can be found on www.shape-up.academy. See you in Berlin! Read more
