Indistinguishable single photons from a quantum dot in a nanopost cavity

Wavelength-tunable sources of single photons are key devices for scaling up optical quantum technologies. In this context, individual quantum dots (QDs) embedded in broadband photonic nanostructures are particularly appealing. The nanopost cavity, which is built with a segment of...

Orientation-tunable correlated Chern insulating states in chiral twisted double bilayer graphene proximitized by WSe2

Moiré flat bands in graphene systems proximitized by transition-metal dichalcogenides (TMDCs) provide a setting where spin-orbit coupling (SOC) can reshape band topology. The crystallographic alignment angle Φ between TMDC and graphene layers is predicted to tune the balance of I...
