Understanding how sound waves travel through disordered materials

A team of researchers lead by the University of Tsukuba have created a new theoretical model to understand the spread of vibrations through disordered materials, such as glass. They found that as the degree of disorder increased, ...

Anti-gravity: How a boat can float upside down

Here on Earth, everything is subject to gravity—it makes objects fall to the ground and rivers flow from higher ground to the sea. We know what would happen without it, thanks to images of astronauts floating around their ...

Vibrational encounters—phonon polaritons meet molecules

Researchers from CIC nanoGUNE BRTA (San Sebastian, Spain), in collaboration with the Donostia International Physics Center (San Sebastián, Spain) and the University of Oviedo (Spain) employed a spectroscopic nanoimaging ...

A Plug-and-play approach to integrated nanoacoustics

From taut strings vibrating in musical instruments to micro-electro-mechanical systems for optoelectronics, vibrations cover an extensive range of applications. At the nanoscale, the study of mechanical vibrations poses several ...

'Floppy' atomic dynamics help turn heat into electricity

Materials scientists at Duke University have uncovered an atomic mechanism that makes certain thermoelectric materials incredibly efficient near high-temperature phase transitions. The information will help fill critical ...

Nanoearthquakes control spin centers in silicon carbide

Researchers from the Paul-Drude-Institut in Berlin, the Helmholtz-Zentrum in Dresden and the Ioffe Institute in St. Petersburg have demonstrated the use of elastic vibrations to manipulate the spin states of optically active ...
