Physics Colloquium: Topological Dynamics from life science to metamaterials
Topological Dynamics from life science to metamaterials
Prof. Camelia Prodan, NJIT
Mechanical systems can display topological characteristics similar to that of topological insulators. In this talk I am going to present such materials from the microtubule to quasiperiodic crystals. The microtubule, the skeleton of every eukaryotic cell, was proposed to be a topological material with the topological edge modes playing an important role in its functioning. I will present our experimental work geared towards measuring the phonon spectrum of individual microtubule, and mapping the differences between regular and cancerous microtubules. A novel experimental platform based on coupled magnetic spinners will be introduced to visualize the mechanical analogous of Quantum Valley Hall Effect, as well as a new system supporting topological edge modes. Practical applications will be discussed.
