Publication: Modulation of Superconductivity across a Lifshitz Transition in Alternating-Angle Twisted Quadrilayer Graphene

Congratulations to Isabelle, Andrew, and Zeyu on their new publication in PRL! By implementing a series of magnetotransport techniques on carefully fabricated twisted quadrilayer graphene (TQG) devices, they discovered that tuning the TQG through flat and dispersive bands via density and displacement field can lead to an enhancement of its superconductivity. Their work highlights the intricate relationship between Fermi surface topology, symmetry-broken states, and superconductivity in TQG, and opens the door to further investigations in multilayer Moire materials with complex bandstructures.
