Metamaterials and Topological Mechanics - Lecture 1

Explore the fascinating world of metamaterials and topological mechanics in this comprehensive lecture by Tom Lubensky from the University of Pennsylvania. Delve into the properties of engineered materials with exotic behaviors not found in nature, such as negative optical indices of refraction and one-way light or vibration waves. Learn about the application of topology in mechanical materials and how it relates to bulk excitation spectra and topological invariants. Discover the concept of topologically protected zero-energy edge states and their implications for creating rigid and supersoft edges in materials. Gain insights into advanced fabrication techniques like 3D printing and their role in creating metamaterials. The lecture covers a wide range of topics, including Maxwell lattices, Kagome lattices, topological characterization, and the transition from Maxwell to elastic limits. Engage with cutting-edge research in this field and understand its potential applications in various industries, from aerospace to civil engineering.
