Controlling the optical properties of solids with acoustic waves
Physicists from Switzerland, Germany, and France have found that large-amplitude acoustic waves, launched by ultrashort laser pulses, can dynamically manipulate the optical response of semiconductors.

Researchers create better light-trapping devices
Anyone who's ever played the drums, tuned a guitar, or even made a wine glass "sing" by circling a finger along its edge knows about resonance. Acoustic resonators, like the cavity of a drum or a half-full wine glass, naturally ...

Microscale rockets can travel through cellular landscapes
A new study from the lab of Thomas Mallouk shows how microscale "rockets," powered by acoustic waves and an onboard bubble motor, can be driven through 3-D landscapes of cells and particles using magnets. The research was ...

Using velocity-induced acoustic oscillations as a standard ruler at cosmic dawn
Our current understanding of physics suggests that there are two main types of matter in the universe known as dark and baryonic matter. Dark matter is made up of material that scientists cannot directly observe, as it does ...
Seeing sound: Scientists observe how acoustic interactions change materials at the atomic level
When exposed to stress and strain, materials can display a wide range of different properties. By using sound waves, scientists have begun to explore fundamental stress behaviors in a crystalline material that could form ...

Artificial materials reconstruct porpoise's echolocation
Over millions of years, porpoises have developed powerful biosonar with high accuracy and intelligence to detect and track prey in noisy underwater environments. The sound source in a porpoise is about one half of the wavelength ...

Study shows the non-exponential decay of a giant artificial atom
To date, research in quantum optics has primarily investigated the relation between light and matter using small atoms interacting with electromagnetic fields that have substantially larger wavelengths. In an unconventional ...
Wired for sound: A third wave emerges in integrated circuits
Optical fibres are our global nervous system, transporting terabytes of data across the planet in the blink of an eye.
