A research team at McGill University has developed a novel device that, at extremely low temperatures, generates particles ...

Phonons are the quantum units of mechanical vibration. They describe how motion propagates through a solid at the smallest possible scales, in much the same way that electrons describe electric ...

WEST LAFAYETTE, Ind. – New findings have solved a longstanding obstacle in research to understand the effects of heat conduction in solid materials, a critical issue in many applications, from energy ...

A authors of this article propose a photoconductive semiconductor switch based on a phonon-assisted absorption mechanism. The ...

A joint project between RIT and the University of Rochester has developed a new squeezed phonon laser that provides precise control over individual particles of sound or vibration. “Light carries ...

Just as overlapping ripples on a pond can amplify or cancel each other out, waves of many kinds—including light, sound and atomic vibrations—can interfere with one another. At the quantum level, this ...

Scientists have observed, quantified and created a new theoretical model of the coupling of two forms of collective atomic excitation, known as magnons and phonons in crystals of the antiferromagnet ...

A research team has discovered ferroelectric phenomena occurring at a subatomic scale in the natural mineral brownmillerite. The team was led by Prof. Si-Young Choi from the Department of Materials ...

Sound engineering: The new device is a chip-based single-phonon directional coupler that carries out controllable phonon splitting. It could enable microscopic on-chip routers and splitters that link ...
