Physicists in the US, Europe and Korea have produced a long-lasting light-driven magnetic state in an antiferromagnetic material for the first time. While their project started out as a fundamental ...
Terahertz light has the ability to control solids at the atomic level, forming chiral structures of left- and right-handedness. Chirality refers to objects that cannot be superimposed to their ...
The research team, led by Andrea Cavalleri, used terahertz light to lift this balance in the non-chiral material boron phosphate (BPO 4), in this way inducing finite chirality on an ultrafast time ...
