Engineers develop a low-cost terahertz camera

Terahertz radiation, whose wavelengths lie between those of microwaves and visible light, can penetrate many nonmetallic materials and detect signatures of certain molecules. These handy qualities could lend themselves to ...

Optical foundations illuminated by quantum light

Optics, the study of light, is one of the oldest fields in physics and has never ceased to surprise researchers. Although the classical description of light as a wave phenomenon is rarely questioned, the physical origins ...

Scientists see spins in a 2D magnet

All magnets—from the simple souvenirs hanging on your refrigerator to the disks that give your computer memory to the powerful versions used in research labs—contain spinning quasiparticles called magnons. The direction ...
