(Phys.org)—Fujifilm is working on a new recording method for optical discs. It has developed the new method through the use of two-photon absorption in order to generate heat, and the report in TechOn! notes that this two-photon ...
(Phys.org)—Two teams working independently have succeeded in entangling a single electron spin with a single photon in a solid-state platform. Both teams describe their process and results in papers they've had published ...
Most electronic data is stored on magnetic hard drives that spin at many thousands of revolutions per minute. To keep pace with ever-growing storage demand, however, achieving greater storage capacities by simply increasing ...

(Phys.org) -- In the early days of chemistry, finding out what happened when two or more chemicals were mixed together led to the development of all manner of new materials and to deriving useful events, such as the production ...
In a leap forward for laser technology, a team at University of California, Santa Barbara, has developed the first violet nonpolar vertical-cavity surface-emitting lasers (VCSELs) based on m-plane gallium nitride semiconductors.
