Twisted bilayer graphene has a rich phase diagram, including superconductivity. Recently,
an unexpected discovery has been the observation of superconductivity in non-twisted …

Compared with electronic phase transitions, structural phase transitions of crystals are
challenging to control owing to the energy cost of breaking dense solid bonds. Recently …

In the presence of a large perpendicular electric field, Bernal-stacked bilayer graphene
(BLG) features several broken-symmetry metallic phases,–as well as magnetic-field-induced …

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

Superconductivity was recently discovered in rhombohedral trilayer graphene (RTG) in the
absence of a moiré potential. Superconductivity is observed proximate to a metallic state …

The group of moiré graphene superconductors keeps growing, and by now it contains
twisted graphene multilayers as well as untwisted stacks. We analyze here the contribution …

We provide a theoretical interpretation of the metallic broken spin-valley (flavor) symmetry
states recently discovered in hole-doped rhombohedral trilayer (ABC) graphene in large …

This is an update of a previous review (Naumis et al 2017 Rep. Prog. Phys. 80 096501).
Experimental and theoretical advances for straining graphene and other metallic, insulating …

We discuss a Kohn-Luttinger-like mechanism for superconductivity in Bernal bilayer
graphene and rhombohedral trilayer graphene. Working within the continuum model …

Recent experiments indicate that crystalline graphene multilayers exhibit much of the
richness of their twisted counterparts, including cascades of symmetry-broken states and …
