25 Nov 2021
Taken from the November 2021 issue of Physics World.

Despite its many useful properties, a particular feature of the “wonder material” graphene, namely the emergent “valley Hall effect”, has been puzzling researchers for a decade, as condensed-matter physicists Luis Foà Torres and Sergio O Valenzuela explain

Since it was first successfully isolated in 2004, the “wonder material” graphene, with its honey
