Explore a 49-minute conference talk on periodic and quasiperiodic moiré crystals presented by Eva Andrei from Rutgers University. Delve into the fascinating world of moiré materials and their unprecedented tunability in band structure, symmetry, and topology. Gain insights into pressing theoretical questions surrounding these materials, including the origin of superconductivity, the nature of correlated states, and the role of topology. Learn about experimental challenges and novel techniques in the field. Discover emerging tunable platforms such as twisted superconductors, topological surface states, quasi-periodic moiré systems, and twisted magnetic materials. Recorded as part of the "Moiré materials: A New Paradigm in Tunable Quantum Matter" conference at the Kavli Institute for Theoretical Physics, this talk offers a comprehensive exploration of cutting-edge research in quantum matter.
