Explore the fascinating world of twisted trilayer graphene through this physics lecture that examines how stacking van der Waals layers creates new opportunities for designing electronic band structure. Discover how weak bonding between layers enables relative twisting and relaxation into distinct local stacking configurations, generating spatially modulated electronic structure across various length scales. Learn about recent measurements revealing the rich interplay between structural and electronic degrees of freedom in twisted trilayer graphene through joint imaging and transport studies. Examine distinct limits of interlayer angles and their resulting electronic character, and understand how these findings inform the broader phase diagram of twisted moiré multilayers and their unique quantum electronic phases. Gain insights into emergent strongly correlated and topological states in 2D quantum materials through research that combines cryogenic electronic transport, scanned probe microscopy, and capacitive sensing techniques to realize, study, and control these novel phases.
