Graphene was first discovered as a sheet structure mechanically exfoliated from a block of
graphite, but in recent years researchers have extended their investigations into this two …

Two-dimensional (2D) ferroics, namely ferroelectric, ferromagnetic, and ferroelastic
materials, are attracting rising interest due to their fascinating physical properties and …

Interactions between electrons and the topology of their energy bands can create unusual
quantum phases of matter. Most topological electronic phases appear in systems with weak …

In magic angle twisted bilayer graphene (TBG), electron-electron interactions play a central
role, resulting in correlated insulating states at certain integer fillings. Identifying the nature …

When the twist angle between two layers of graphene is approximately 1.1°, interlayer
tunnelling and rotational misalignment conspire to create a pair of flat bands that are known …

Flat bands in magic-angle twisted bilayer graphene (MATBG) have recently emerged as a
rich platform to explore strong correlations, superconductivity,,–and magnetism,,. However …

The discovery of magic angle twisted bilayer graphene has unveiled a rich variety of
superconducting, magnetic, and topologically nontrivial phases. Here, we show that the zero …

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 …

Graphene, a two dimensional monoatomic thick building block of a carbon allotrope, has
emerged as an exotic material of the 21st century, and received world-wide attention due to …

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 …
