Strongly Correlated 2D Materials and Oxides

Highly correlated materials are excellent materials whose electronic properties are governed by strong correlations between electrons present in it. 2D layered materials, whose valence band structure is composed of one flat band and two Dirac bands, can host a broad range of tunable topological and strongly correlated electronic phases. The present chapter outlines strong correlations in magic-angle twisted bilayer graphene, complex metal oxide systems, transition metal dichalcogenides, etc. In such type of correlated electron materials, the interactions between the electronic charges, orbitals, spin, and the lattice produce a rich variety of electronic phases and self-organization. The cooperation among these correlated electronic phases can steer the emanation of surprising electronic phenomena and also of interesting functionalities through their responses to external fields.
