Topological Wigner Crystal and FQSH in Moire Systems

Explore a 34-minute conference talk on topological Wigner crystals and fractional quantum spin Hall (FQSH) effects in moiré systems, presented by Yahui Zhang from Johns Hopkins University. Delve into the cutting-edge research on moiré materials, which offer unprecedented tunability in band structure, symmetry, and topology. Gain insights into the rich platform these materials provide for investigating various quantum phenomena within a unified approach. Learn about pressing theoretical questions in the field, including the origin of superconductivity, the nature of correlated states, and the role of topology in these systems. Discover the experimental challenges and novel techniques being developed to study moiré materials. Examine 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 contributes to the broader discussion on advancing our understanding of quantum matter and its potential applications.
