Cooling of a trapped ion to the quantum regime

Neutral atoms and charged ions can be cooled down to extremely low temperatures (i.e., to microkelvins, 1 millionth of a degree above absolute zero) using laser techniques. At these low temperatures, the particles have often ...

Simple self-charging battery offers power solutions for devices

A new type of battery combines negative capacitance and negative resistance within the same cell, allowing the cell to self-charge without losing energy, which has important implications for long-term storage and improved ...

Want to catch a photon? Start by silencing the sun

Researchers at Stevens Institute of Technology have created a 3-D imaging system that uses light's quantum properties to create images 40,000 times crisper than current technologies, paving the way for never-before seen LIDAR ...

Advancement simplifies laser-based medical imaging

Photoacoustic imaging, a technique for examining living materials through the use of laser light and ultrasonic sound waves, has many potential applications in medicine because of its ability to show everything from organs ...

Researchers create new state of light

For 20 years, researchers have studied how light rotates around a longitudinal axis parallel to the direction light travels. But could it move in other ways? After two years of research, and thanks to a sabbatical, University ...

Radio waves detect particle showers in a block of plastic

When neutrinos crash into water molecules in the billion-plus tons of ice that make up the detector at the IceCube Neutrino Observatory in Antarctica, more than 5,000 sensors detect the light of subatomic particles produced ...
