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 ...
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 ...
To detect the quantum friction of empty space, scientists are going for a spin. A twirling nanoparticle, suspended in a laser beam inside of a vacuum, can measure tiny twisting forces, making it the ...
Researchers at Tohoku University have achieved a significant advancement in opto-magnetic technology, observing an opto-magnetic torque approximately five times more efficient than in conventional ...
