'Space-time cloak' to conceal events revealed in new study

(PhysOrg.com) -- The study, by researchers from Imperial College London, involves a new class of materials called metamaterials, which can be artificially engineered to distort light or sound waves. With conventional materials, ...

Crystal creates a supercontinuum breakthrough

Researchers have generated a wide range of colors from a single laser after discovering a new process for achieving so-called "supercontinuum generation."

'Spooky action at a distance' aboard the ISS

(Phys.org) —Albert Einstein famously described quantum entanglement as "spooky action at distance"; however, up until now experiments that examine this peculiar aspect of physics have been limited to relatively small distances ...

Two photons strongly coupled by glass fiber

Usually, light waves do not interact with each other. Coupling of photons with other photons is only possible with the help of special materials and very intense light. Scientists in Vienna have now created the strongest ...

Researchers catch light in a funnel

Professor Ronny Thomale holds a chair for theoretical condensed matter physics, the TP1, at the Julius-Maximilian University of Würzburg. The discovery and theoretical description of new quantum states of matter is a prime ...
