(Nanowerk News) Just as electrons flow through an electrical conductor, magnetic excitations can travel through certain materials. Such excitations, known in physics as "magnons" in analogy to the ...

Levitation is often thought of as the realm of magicians or The Jetsons, but it is technically possible. That said, the tech seems to be moving pretty slowly. Now, researchers at the University of ...

Physicists at NYU have discovered a new type of time crystal—an exotic state of matter whose particles rhythmically “tick” while levitating on sound waves.

Research undertaken by the Universidad Carlos III de Madrid (UC3M) has concluded that sound can be directed to a certain place if the sound waves’ symmetry is broken. In order to carry out this work, ...

A research team at City University of Hong Kong (CityU) has discovered a new type of sound wave: the airborne sound wave vibrates transversely and carries both rotation and orbital angular momentum ...

Be it water, light or sound: waves usually propagate in the same way forwards as in the backward direction. As a consequence, when we are speaking to someone standing some distance away from us, that ...

Researchers have found a way to make materials that are normally opaque to sound waves completely transparent. Their system involves placing acoustic relays at strategic locations so that sound waves ...
