Interacting Narrow Bands of Twisted Bilayer Graphene in Magnetic Field

Explore the fascinating world of twisted bilayer graphene in a magnetic field through this 44-minute lecture by Oskar Vafek at the International Centre for Theoretical Sciences. Delve into the intricacies of interacting narrow bands and their behavior under magnetic influence. Learn about emergent electronic, magnetic, and topological phenomena in two-dimensional synthetic structures of quantum materials. Gain insights into the strong interplay between electronic correlations, spin-orbit coupling, crystal structure, symmetry, and topology in reduced dimensionality systems. Discover how frustrated coupling across 2D interfaces and enhanced interlayer interactions lead to new electronic band structures and emergent behaviors. Part of the "Engineered 2D Quantum Materials" program, this talk contributes to a broader discussion on artificially engineered heterostructures, including oxide interfaces, van der Waals materials, and other novel moire or layered materials.
