Using a laser to stimulate a photocurrent and a magnetic field to control it, researchers have devised a scheme for measuring a current’s flow stream. Why there’s a need to assess current-flow ...

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 ...

We have repeated Casimir's experiment 1 designed to measure the variation with temperature of the penetration depth (λ) of a magnetic field into a massive superconductor. The principle of the ...
