A closed door feels absolute. Light stays in one room, darkness settles in the next, and the boundary seems obvious enough to ...

Aug. 22, 2024 — SandiaNational Laboratories and Arizona State University are collaborating to combine quantum technology and large-scale optical systems into integrated microsystems. Nils Otterstrom, ...

Researchers report their insights on the emerging field of complex frequencies excitations, a recently introduced scheme to control light, sound and other wave phenomena beyond conventional limits.

Invisible infrared waves are emitted by IR LEDs and detected by photodiodes to enable devices like remotes, automatic ...

A team of scientists has succeeded in cooling traveling sound waves in wave-guides considerably further than has previously been possible using laser light. This achievement represents a significant ...

Gravitational waves are ripples in spacetime produced by violent cosmic events, such as the merging of black holes. So far, direct detections have relied on measuring tiny distance changes over ...

High-frequency light is useful. The higher the frequency of light, the shorter its wavelength – and the shorter the wavelength, the smaller the objects and details the light can be used to see. So ...

NEW YORK, April 1, 2025 — Researchers at the Advanced Science Research Center at the CUNY Graduate Center (CUNY ASRC) and at Florida International University report in the journal Science their ...

Gravitational waves from violent cosmic events distort spacetime. A new study proposes detecting them by observing how they alter light emitted by atoms, pending experiments. (Nanowerk News) ...
