Explore the concept of ergodicity breaking in flatbands through this insightful lecture by Alexei Andreanov from the International Centre for Theoretical Sciences. Delve into the complex world of periodically and quasi-periodically driven systems as part of a comprehensive program on quantum matter dynamics. Gain valuable insights into topics such as terahertz and infrared driven quantum matter, shaken optical lattices, Floquet time crystals, and localization-delocalization physics in quasi-periodically driven systems. Discover the interplay between closed quantum systems, open quantum systems, and gauge theory of coupling between matter and radiation. Enhance your understanding of cutting-edge research in quantum simulation experiments and their interpretation in scenarios where traditional numerical calculations fall short.
