Topological mechanical states in geometry-driven hyperuniform materials

Activity: Other Engagements › Other Activity

Description

A belated yet very much welcoming acceptance outcome of my PhD work in collaboration with researchers at the UTS TechLab. Adopting a hyperuniform geometry (disordered at a local scale, yet ordered at a global scale) generated by Lloyd's algorithm as an arrangement of cells, we have explored its vibrational properties where we find energy localisation around topological defects (non-hexagonal cells in a two-dimensional cellular geometry). The energy localisation around dynamically arrested topological defects along the Lloyd iterations results in opening up band-gaps in dispersion diagrams, suggesting the robust dynamic mechanism influences a broad spectrum of disordered systems, from synthetic materials to biological structures guided by stigmergic interactions. More on the paper -- or happy to chat in person. :)
