An experiment resolves the tiny momentum transferred from an individual gas molecule to a levitated nanoparticle.

A technique known as ghost imaging has been adapted so that an object can be imaged by discarding all photons that interact with it. Split a beam of light in two and direct one beam (the reference) to ...

An ultrafast optical technique uncovers new clues to the origin of bulk polarization in quantum ferroelectric materials. In classical ferroelectric materials, electric dipoles in the material line up ...
