Near a magic twist angle, bilayer graphene transforms from a weakly correlated Fermi liquid
to a strongly correlated two-dimensional electron system with properties that are …

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 …

Twisted bilayer graphene with a twist angle of around 1.1° features a pair of isolated flat
electronic bands and forms a platform for investigating strongly correlated electrons. Here …

Motivated by the recent observation of an anomalous Hall effect in twisted bilayer graphene,
we use a lowest Landau level model to understand the origin of the underlying symmetry …

We model the newly synthesized magic-angle-twisted bilayer graphene superconductor with
two px, y-like Wannier orbitals on the superstructure honeycomb lattice, where the hopping …

According to electronic structure theory, bilayer graphene is expected to have anomalous
electronic properties when it has long-period moiré patterns produced by small …

Twisted bilayer graphene (TBLG) is one of the simplest van der Waals heterostructures, yet it
yields a complex electronic system with intricate interplay between moiré physics and …

Quantum states of quasiparticles in solids are dictated by symmetry. We have experimentally
demonstrated quantum states of Dirac electrons in a two-dimensional quasicrystal without …

We theoretically study the optical absorption property of twisted bilayer graphenes with
various stacking geometries and demonstrate that the spectroscopic characteristics serve as …

Bilayer graphene has been predicted to host a moiré miniband with flat dispersion if the
layers are stacked at specific twist angles known as the'magic angles',. Recently, twisted …
