- Moiré materials realized by controlling the twistbetween different atomic layers represent anemerging family of crystals with unique electronicpropertie
- At certain magic angles the electron velocity isgreatly reduced, leading to spectacular effectslike superconductivity, and magnetism
- We demonstrate the emergencesuperconductivity, and correlated insulators in analternating twist four-layer graphene structure
- This achievement is important as itdemonstrates magic angle hierarchy in graphenemultilayers, achieved through accurate control ofmultiple twist angles in a moiré material
