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 …

In conventional superconductors, Cooper pairing occurs between electrons of opposite spin.
We observe spin-polarized superconductivity in Bernal bilayer graphene when doped to a …

Reducing the energy bandwidth of electrons in a lattice below the long-range Coulomb
interaction energy promotes correlation effects. Moiré superlattices—which are created by …

Ferromagnetism is most common in transition metal compounds where electrons occupy
highly localized d orbitals. However, ferromagnetic order may also arise in low-density two …

We review recent work on low-frequency Floquet engineering and its application to quantum
materials driven by light, focusing on van der Waals systems hosting Moiré superlattices …

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 …

Magnetism typically arises from the joint effect of Fermi statistics and repulsive Coulomb
interactions, which favours ground states with non-zero electron spin. As a result, controlling …

Emergent phenomena arising from the collective behaviour of electrons is expected when
Coulomb interactions dominate over the kinetic energy, and one way to create this situation …

Two graphene monolayers twisted by a small magic angle exhibit nearly flat bands, leading
to correlated electronic states. Here we study a related but different system with reduced …

Fractional Chern insulators realize the remarkable physics of the fractional quantum Hall
effect (FQHE) in crystalline systems with Chern bands. The lowest Landau level (LLL) is …
