Explore the fascinating world of quantum physics in this lecture on cold atoms, quantum simulation, and driven quasicrystals. Delve into the first part of David Weld's presentation, which is part of the "Periodically and Quasi-Periodically Driven Complex Systems" program organized by the International Centre for Theoretical Sciences. Learn about cutting-edge research in quantum systems, including topics such as terahertz and infrared driven quantum matter, shaken optical lattices, Floquet time crystals, and localization-delocalization physics in quasi-periodically driven systems. Gain insights into the interplay between theory and experiment in quantum simulation, and discover how these concepts apply to complex systems in physics. This hour-long lecture offers a unique opportunity to engage with advanced concepts in quantum physics and their applications in modern research.
