Spin-orbit coupled graphene multilayers: correlations, superconductivity and topology
Abstract: Crystalline graphene multilayers present a rich playground to explore correlated electronic phenomena in an ultra-clean setting, free of the inhomogeneities ubiquitous in their twisted counterparts. For instance, Bernal bilayer graphene (BLG) and rhombohedral trilayer graphene both exhibit several symmetry-broken metallic phases at low temperature, as well as superconductors with different pairing symmetries. Moreover, placing a WSe2 monolayer on BLG was shown to promote Cooper pairing to an extraordinary degree, with an order-of-magnitude enhancement of Tc [1].
