Quantum effects are physical phenomena that cannot be explained accurately with classical mechanics alone. They arise from the wave-like and probabilistic behavior of matter and light: energy levels ...

A new quantum device can generate precisely controlled bursts of sound-like particles, or phonons, by forcing electrons through an ultra-thin crystal at extremely low temperatures. The surprising ...

Physicists at MIT have achieved a major feat, capturing a bizarre quantum effect called second sound on film, where heat ripples through matter like a wave instead of spreading gradually. First ...

Iron screws and other so-called ferromagnetic materials are made up of atoms with electrons that act like little magnets. Normally, the orientations of the magnets are aligned within one region of the ...

Add Yahoo as a preferred source to see more of our stories on Google. When you turn on a lamp to brighten a room, you are experiencing light energy transmitted as photons, which are small, discrete ...

Researchers have proposed a new way of using quantum light to 'see' quantum sound. A new paper reveals the quantum-mechanical interplay between vibrations and particles of light, known as photons, in ...

Sound is usually treated as the most familiar of physical phenomena, the background noise of daily life rather than a frontier of fundamental physics. Yet in laboratories around the world, carefully ...

A crucial building block for quantum computers based on sound has been shown to work for the first time. One popular way of building quantum computers is to encode information into quantum states of ...

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, which ...

A quiet revolution is taking shape in the world of physics, and it doesn't rely on exotic particles or massive particle colliders. Instead, it begins with something much more familiar—sound.

The quantum size effect (QSE) is the change in a material's electronic, optical, magnetic, or thermal behavior when one or more of its dimensions become small enough to confine charge carriers such as ...

When you turn on a lamp to brighten a room, you are experiencing light energy transmitted as photons, which are small, discrete quantum packets of energy. These photons must obey the sometimes strange ...
