Trapped electrons traveling in circular loops at extreme speeds inside graphene quantum dots are highly sensitive to external magnetic fields and could be used as novel magnetic field sensors with ...

Spin device: in this diagram of the spin valve the nanowire runs between a source and drain (both shown in gold) and the locations of the two quantum dots on the nanowire are denoted by the dashed ...

Magnetism and superconductivity are often thought to be incompatible with each other. However, Martin Lange and colleagues from the Catholic University of Leuven in Belgium have now shown that a ...
