Giant intrinsic chirality from planar dielectric nanostructures

Harvard researchers have developed a metasurface comprising a single planar layer of nanostructures exhibiting strong optical chirality in transmission. This means it can let circularly polarized light of one polarization ...

'Colossal' Magnetic Effect Under Pressure

(PhysOrg.com) -- Millions of people today carry around pocket-sized music players capable of holding thousands of songs, thanks to the discovery 20 years ago of a phenomenon known as the “giant magnetoresistance effect,” ...
