Evidence for Flat Band Dirac Superconductor Originating from Quantum Geometry
Haidong Tian, Shi Che, Tianyi Xu +7
In a flat band superconductor, the charge carriers' group velocity vF is extremely slow, quenching their kinetic energy. The emergence of superconductivity thus appears paradoxical…
Strange metal behavior of the Hall angle in twisted bilayer graphene
Rui Lyu, Zachary Tuchfeld, Nishchhal Verma +6
Twisted bilayer graphene (TBG) with interlayer twist angles near the magic angle hosts flat bands and exhibits correlated states including Mott-like insulato…
Helical Edge States and Quantum Phase Transitions in Tetralayer Graphene
Shi Che, Yanmeng Shi, Jiawei Yang +9
Helical conductors with spin-momentum locking are promising platforms for Majorana fermions. Here we report observation of two topologically distinct phases supporting helical edge…
Correlated Insulating and Superconducting States in Twisted Bilayer Graphene Below the Magic Angle
Emilio Codecido, Qiyue Wang, Ryan Koester +9
The emergence of flat bands and correlated behaviors in 'magic angle' twisted bilayer graphene (tBLG) has sparked tremendous interest, though many aspects of the system are under i…
