A grand family of two-dimensional (2D) materials and their heterostructures have been
discovered through the extensive experimental and theoretical efforts of chemists, material …

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 …

The behaviour of strongly correlated materials, and in particular unconventional
superconductors, has been studied extensively for decades, but is still not well understood …

A van der Waals heterostructure is a type of metamaterial that consists of vertically stacked
two-dimensional building blocks held together by the van der Waals forces between the …

Materials with flat electronic bands often exhibit exotic quantum phenomena owing to strong
correlations. An isolated low-energy flat band can be induced in bilayer graphene by simply …

Twisted van der Waals heterostructures have latterly received prominent attention for their
many remarkable experimental properties and the promise that they hold for realizing …

Superconductivity can occur under conditions approaching broken-symmetry parent states.
In bilayer graphene, the twisting of one layer with respect to the other at 'magic'twist angles …

The quantum Hall (QH) effect, quantized Hall resistance combined with zero longitudinal
resistance, is the characteristic experimental fingerprint of Chern insulators—topologically …

Recent advances in the isolation and stacking of monolayers of van der Waals materials
have provided approaches for the preparation of quantum materials in the ultimate two …

The electronic properties of heterostructures of atomically thin van der Waals crystals can be
modified substantially by moiré superlattice potentials from an interlayer twist between …
