Laser Cooling Chills Radium Ions For The First Time

Researchers have successfully used laser cooling on radium ions for the first time. Given that lasers are known for heating things up, laser cooling may seem a contradiction in terms. However, scientists have devised a way to use the technology to achieve unparalleled levels of cold. Radium is the heaviest alkaline earth element, and the [...]

Terahertz light can control some of the essential quantum properties of superconducting states, report researchers. Jigang Wang patiently explains his latest discovery in quantum control that could lead to superfast computing based on quantum mechanics: He mentions light-induced superconductivity without energy gap. He brings up forbidden supercurrent quantum beats. And he mentions terahertz-speed symmetry breaking. [...]

Physicists have looked for deviations from standard quantum mechanics, testing whether quantum mechanics requires a more complex set of mathematical rules. A research team led by Philip Walther at the University of Vienna designed a photonic experiment using exotic metamaterials, which were fabricated at the University of California Berkeley. Their experiment supports standard quantum mechanics [...]

A technique currently applied in the field of photonics could help predict rogue wave events on the ocean surface, along with other extreme natural phenomena. Stretching time scales to explore extreme events in nature is possible, according to a team from the Institut FEMTO-ST, which used an innovative measurement technique enabling the capture of such [...]

A tiny radio whose building blocks are the size of two atoms has been developed by Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences. Built out of an assembly of atomic-scale defects in pink diamonds, it is the world’s smallest radio receiver. The device can withstand extremely harsh environments and [...]
