Twisted bilayer graphene has a rich phase diagram, including superconductivity. Recently,
an unexpected discovery has been the observation of superconductivity in non-twisted …

This article reviews the theoretical and experimental work related to the electronic properties
of bilayer graphene systems. Three types of bilayer stackings are discussed: the AA, AB, and …

Abstract Fractional Chern insulators (FCIs) are lattice analogues of fractional quantum Hall
states that may provide a new avenue towards manipulating non-Abelian excitations. Early …

The interplay between strong electron–electron interactions and band topology can produce
electronic states that spontaneously break symmetries. The discovery of flat bands in magic …

We review the electronic properties of bilayer graphene, beginning with a description of the
tight-binding model of bilayer graphene and the derivation of the effective Hamiltonian …

Electronic states at domain walls in bilayer graphene are studied by analyzing their four-and
two-band continuum models, by performing numerical calculations on the lattice, and by …

Abstract Two‐dimensional (2D) materials exhibit massive potential for research and
development in the scientific world due to the unique electrical, optical, thermal, and …

Chirally stacked N-layer graphene systems with N≥ 2 exhibit a variety of distinct broken
symmetry states in which charge density contributions from different spins and valleys are …

Non-trivial interacting phases can emerge in elementary materials. As a prime example,
continuing advances in device quality have facilitated the observation of a variety of …

The quantum anomalous Hall (QAH) effect—a macroscopic manifestation of chiral band
topology at zero magnetic field—has been experimentally realized only by the magnetic …
