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 …

Moiré superlattices, have recently emerged as a platform upon which correlated physics and
superconductivity can be studied with unprecedented tunability,,–. Although correlated …

Moiré graphene systems have attracted considerable attention in the past 3 years because
they exhibit exotic phenomena including correlated insulating states, unconventional …

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

Graphene moiré superlattices show an abundance of correlated insulating, topological, and
superconducting phases. Whereas the origins of strong correlations and nontrivial topology …

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 …

We derive the explicit Hamiltonian of twisted bilayer graphene (TBG) with Coulomb
interaction projected into the flat bands and study the symmetries of the Hamiltonian. First …

In a recent experiment (Lin et al 2021 arxiv: 2112.07841 [cond-mat. str-el]), the
superconducting phase hosted by a heterostructure of mirror-symmetric twisted trilayer …

When two monolayers of graphene are stacked with a small relative twist angle, the resulting
band structure exhibits a remarkably flat pair of bands at a sequence of “magic angles” …

We show that the entire continuous model of twisted bilayer graphene (TBG)(and not just the
two active bands) with particle-hole symmetry is anomalous and hence incompatible with …
