Correlations in Moire Flat Bands
Coordinators: Andrey Chubukov, Cory Dean, Eun-Ah Kim, and Andrea Young
Electrons in two dimensional lattices form the basis of our understanding of correlated ground states in quantum condensed matter physics, including topological order and unconventional superconductivity. Recently, moire superlattices in two dimensional van der Waals heterostructures have emerged as a new experimental system for studying correlated physics, affording new degrees of experimental control. Propelled by recent advances in fabrication, which enable the production of controlled twist-angle devices with low disorder, recent experiments demonstrated the existence of unexpected insulating states and superconductivity in graphene- and hexagonal boron nitride based structures. The purpose of this program is to gather leading experimental and theoretical experts on various aspects of two dimensional materials and correlation effects in low dimensional electron systems to discuss key questions and prospects in these and related materials.
