Add to Calendar 9/26/2018 4:00 pm 9/26/2018 America/Chicago Physics Colloquium: "Topological Dynamics from life science to metamaterials" DESCRIPTION:

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 functioning1. 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 Effect2, as well as a new system supporting topological edge modes3. Practical applications will be discussed4.
