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 …

Pristine graphene has been considered one of the most promising materials because of its
excellent physical and chemical properties. However, various defects in graphene produced …

When single layers of 2D materials are stacked on top of one another with a small twist in
orientation, the resulting structure often involves incommensurate moiré patterns. In these …

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 …

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 …

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 …

A remarkable recent experiment has observed Mott insulator and proximate superconductor
phases in twisted bilayer graphene when electrons partly fill a nearly flat miniband that …

Correlated insulators and superconductivity have been observed in “magic-angle” twisted
bilayer graphene, when the nearly flat bands close to neutrality are partially filled. While a …

In this paper we present a paradigmatic tight-binding model for single-layer as well as
multilayered semiconducting MoS 2 and similar transition metal dichalcogenides. We show …

We devise a model to explain why twisted bilayer graphene exhibits insulating behavior
when ν= 2 or 3 charges occupy a unit moiré cell, a feature attributed to Mottness per …
