Covers superconductivity in magic-angle twisted bilayer graphene, twisted WSe2 bilayers and rhombohedral multilayer graphene, with the open questions on pairing, gap structure and symmetry. The main takeaway is that superconductivity in magic-angle graphene is well documented by transport and tunneling, while its pairing mechanism, its relation to correlated insulators and its chiral or nematic character remain contested. The reports in twisted WSe2 and rhombohedral graphene are more recent, and the rhombohedral result is still a preprint.

## Sample findings

- Superconductivity was reported in magic-angle twisted bilayer graphene near a twist angle of about 1.1 degrees, with zero-resistance states up to a critical temperature of 1.7 K at carrier densities of order 10^11 cm^-2.
- Superconductivity up to 3 K was reported close to filling factor -2 in magic-angle bilayer graphene, together with further superconducting domes near filling 0 and plus or minus 1 and states with non-zero Chern numbers.
