Twist angle physics in graphene based van der Waals heterostructures
… decoupled, allowing us to put independent quantum Hall edge modes in both layers. We study the edge state interactions in this system, culminating in the formation of a quantum spin Hall state in twisted bilayer graphene. In the small twist angle limit, interlayer interactions are strong …

Magnetotransport in superconductor to semiconductor junctions: multiple Andreev reflections and coupling to quantum hall states
… the maximum increased when the sample was in a quantum Hall state due to the reduction in the number of conduction channels. Samples with a shorter length showed a zero bias resistance minimum when the magnetic field was tuned between quantum Hall states and a maximum otherwise. The minimum is a …
