Superconductivity has been observed in moiré systems such as twisted bilayer graphene,
which host flat, dispersionless electronic bands. In parallel, theory work has discovered that …

The discovery of correlated states and superconductivity in magic-angle twisted bilayer
graphene (MATBG) established a new platform to explore interaction-driven and topological …

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

Two-dimensional materials have attracted significant interest and investigation since the
marvellous discovery of graphene. Due to their unique physical, mechanical and optical …

We propose magic-angle helical trilayer graphene (HTG), a helical structure featuring
identical rotation angles between three consecutive layers of graphene, as a unique and …

Alternating twist multilayer graphene (ATMG) has recently emerged as a family of moiré
systems that share several fundamental properties with twisted bilayer graphene, and are …

We present comprehensive theoretical studies on the lattice relaxation and the electronic
structures in general nonsymmetric twisted trilayer graphenes. By using an effective …

Moiré superlattices formed by twisting trilayers of graphene are a useful model for studying
correlated electron behaviour and offer several advantages over their formative bilayer …

Moiré superlattices that consist of two or more layers of 2D materials stacked together with a
small twist angle have emerged as a tunable platform to realize various correlated and …

Twisted stacking of van der Waals materials with moiré superlattices offers a new way to
tailor their physical properties via engineering of the crystal symmetry. Unlike well-studied …
