The 'spin-transfer torque effect' could provide a powerful means of controlling the orientation of spins with electric currents rather than magnetic fields in future spintronic devices. Quantitative ...

Materials that crystallize in diamond-related lattices, with Si and GaAs as their prime examples, are at the foundation of modern electronics. Simultaneously, inversion asymmetries in their crystal ...

Twisted light: self-torque could be used to manipulate molecules. (Courtesy: iStock/VikaSuh) Physicists in Spain and the US have shown that the orbital angular momentum, or twistedness, of light can ...
