For applications in spin-based electronics and quantum computation, it is crucial to understand quantitively how the electron spin is coupled to the orbital degrees of freedom. In bilayer graphene this is a notoriously difficult task, given the tiny size of the energy scales involved. Researchers from RWTH Aachen University have now managed to accurately measure the spin-orbit coupling in single-electron bilayer graphene quantum dots, exploiting the extreme energy sensitivity of a double-dot device. The result has been reported in Nature Communications.
