Quantum effects are the surprising and often counterintuitive phenomena that occur at the nanoscale, where the laws of classical physics break down and the principles of quantum mechanics dominate.

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 ...

Quantum sounds: Hong Qiao (left) and Chris Conner working in Andrew Cleland’s lab at the University of Chicago. (Courtesy: Joel Wintermantle) Sound is very much a part of the classical, macroscopic ...

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 ...

Scientists are learning how to temporarily reshape materials by nudging their internal quantum rhythms instead of blasting ...

Collective behavior is an unusual phenomenon in condensed-matter physics. When quantum spins interact together as a system, ...

Quantum mechanics dictates sensitivity limits in the measurements of displacement, velocity and acceleration. A recent experiment at the Niels Bohr Institute probes these limits, analyzing how quantum ...

In the lab: PhD candidate Peter Serles places a sample of magnetene in the atomic force microscope. New measurements and simulations of this material show that its ...

Scientists have shown that it may be possible to transform materials simply by triggering internal quantum ripples rather ...

Researchers have achieved quantum "alchemy" that allows them to alter the properties of materials using high-powered ...

A membrane resonator (central white square) is in its 'phononic crystal' shield of cross-shaped holes. Even though the membrane is nearly the size of a flea (0.5mm), its motion follows the laws of ...
