Anomalous Quantum Oscillations in a Heterostructure of Graphene on a Proximate Quantum Spin Liquid

V. Leeb, K. Polyudov, S. Mashhadi +4

The quasi two-dimensional Mott insulator $\alpha$-RuCl${}_3$ is proximate to the sought-after Kitaev quantum spin liquid (QSL). In a layer of $\alpha$-RuCl${}_3$ on graphene the dominant Kitaev…
