Moiré Flatland: Condensed Matter Physics Overview
This lecture covers the properties of van der Waals materials such as graphene, hBN, MoS₂, and wse₂, discussing their classification as insulators, semiconductors, semimetals, or metals. It also explores the tunable superconductivity in magic-angle twisted trilayer graphene, charged skyrmions, and the topological origin of superconductivity in magic-angle graphene. Additionally, it delves into Pauli-limit violation and re-entrant superconductivity in moiré graphene, fractional Chern insulators in magic-angle twisted bilayer graphene, and stacking-engineered ferroelectricity in bilayer boron nitride.
