Scientists 'squeeze' light one particle at a time

A team of scientists has successfully measured particles of light being "squeezed", in an experiment that had been written off in physics textbooks as impossible to observe.

Semiconductor scientists discover effect that was thought impossible

A physical effect known as superinjection underlies modern light-emitting diodes (LEDs) and lasers. For decades this effect was believed to occur only in semiconductor heterostructures—that is, structures composed of two ...

X-ray laser takes aim at cosmic mystery

Scientists have used powerful X-rays from the Linac Coherent Light Source (LCLS) at the SLAC National Accelerator Laboratory, to study and measure, in atomic detail, a key process at work in extreme plasmas like those found ...

Scientists discover a new phase of high-density, ultra-hot ice

The outer planets of our solar system, Uranus and Neptune, are water-rich gas giants. These planets have extreme pressures 2 million times the Earth's atmosphere. They also have interiors as hot as the surface of the sun. ...

Creating light sources for nanochips

(PhysOrg.com) -- "One of the most important goals in the optics community is to create and manipulate light on chip," Yinan Zhang tells PhysOrg.com. "This is especially important when it comes to improving the performance ...
