Magic-angle (θ= 1.0 5°) twisted bilayer graphene (MATBG) has shown two seemingly
contradictory characters: the localization and quantum-dot-like behavior in STM …

The emergence of superconductivity and correlated insulators in magic-angle twisted bilayer
graphene (MATBG) has raised the intriguing possibility that its pairing mechanism is distinct …

Electronic states in quasicrystals generally preclude a Bloch description, rendering them
fascinating and enigmatic. Owing to their complexity and scarcity, quasicrystals are …

In condensed-matter systems, higher temperatures typically disfavour ordered phases,
leading to an upper critical temperature for magnetism, superconductivity and other …

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 …

When two sheets of graphene are stacked on top of each other with a small twist of angle
θ≈ 1.1° between them, theory predicts the formation of a flat electronic band,. Experiments …

Quantum materials have attracted much attention in recent years due to their exotic and
incredible properties. Among them, van der Waals materials stand out due to their weak …

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 …
