A quiet revolution is taking shape in the world of physics, and it doesn’t rely on exotic particles or massive particle ...

The quantum ground state of an acoustic wave of a certain frequency can be reached by completely cooling the system. In this way, the number of quantum particles, the so-called acoustic phonons ...

MIT researchers observe a “second wave” of heat in superfluid helium, confirming that heat propagates like sound.

Molecules are complex and messy systems, constantly vibrating ... that when a molecule exchanges phonons -- quantum-mechanical particles of sound -- with its environment, this produces a ...

Scientists at the University of Innsbruck under the leadership of Hanns-Christoph Nägerl have successfully observed anyons, ...

“Sound doesn’t travel in a vacuum ... So it is crucial to understand if quantum mechanics breaks down for systems of larger size,” says Fadel. As researchers delve deeper into quantum ...

A team of scientists at the Max Planck Institute for the Science of Light led by Dr. Birgit Stiller has succeeded in cooling traveling sound waves in waveguides considerably further than has ...
