We construct a van der Waals heterostructure consisting of three graphene layers stacked with alternating twisting angles $\pm\theta$. At the average twist angle $\theta\sim 1.56^{\circ}$, a theoretically predicted magic angle for the formation of flat electron bands, narrow conduction and valence moir\'e bands appear together with a linearly dispersing Dirac band. Upon doping the half-filled moir\'e valence band with holes, or the half-filled moir\'e conduction band with electrons…

New mechanism and exact theory of superconductivity from strong repulsive interaction
TLDR
It is shown that pairing can be induced by correlated multiparticle tunneling processes that favor two itinerant carriers to be close together, and offers a realistic new route to realizing finite angular momentum superfluidity of spin-polarized fermions in optical lattice.

Tunable spin-polarized correlated states in twisted double bilayer graphene
TLDR
Twisted double bilayer graphene devices show tunable spin-polarized correlated states that are sensitive to electric and magnetic fields, providing further insights into correlated states in two-dimensional moiré materials.
Unconventional superconductivity in magic-angle graphene superlattices
TLDR
The realization of intrinsic unconventional superconductivity is reported—which cannot be explained by weak electron–phonon interactions—in a two-dimensional superlattice created by stacking two sheets of graphene that are twisted relative to each other by a small angle.

TLDR
Evidence is presented that near three-quarters of the filling of the conduction miniband, these enhanced interactions drive the twisted bilayer graphene into a ferromagnetic state, and measurements suggest that the system may be an incipient Chern insulator.

TLDR
A local spectroscopic technique is introduced using a scanning tunnelling microscope to detect a sequence of topological insulators in MATBG with Chern numbers C  = ±1, ±2 and ±3, which form near filling factors of ±3, ±3 and ±1 electrons per moiré unit cell, respectively, and are stabilized by modest magnetic fields.
Untying the insulating and superconducting orders in magic-angle graphene
TLDR
Tuning the electronic interactions by changing the dielectric environment of twisted bilayer graphene reveals the disappearance of the insulating states and their replacement by superconducting phases, suggesting a competition between the two phases.
Correlated insulator behaviour at half-filling in magic-angle graphene superlattices
TLDR
It is shown experimentally that when this angle is close to the ‘magic’ angle the electronic band structure near zero Fermi energy becomes flat, owing to strong interlayer coupling, and these flat bands exhibit insulating states at half-filling, which are not expected in the absence of correlations between electrons.
