Controlling a twist of light in time could lead to ultra-fast nanomagnetism applications
The interaction of light, or photons, with matter underlies applications from imaging devices to fibre optic transmission of data to quantum computers. Twisted light (light exhibiting orbital angular momentum) interacts in unique ways with matter, and harnessing its power could open the door to novel experiments and applications resulting from the production of mechanical motion in nanoscale matter with photons. Recently, scientists demonstrated the ability to vary the twist in time with a light pulse created using high-frequency harmonics. With the EU-funded ATTOSTRUCTURA project, these scientists are developing the theoretical and experimental foundations for ultra-fast magnetism exploiting ultra-short X-rays with angular momenta. It could be a path to pioneering high-rate magnetic recording.
