At the smallest scales of nature, the rules of the world shift in ways that can feel unsettling and beautiful at the same time. Matter no longer behaves like solid objects moving along clear paths.

Researchers from the University of Vienna have reported quantum interference in metallic nanoparticles. These little spheres were made of between 5,000 and 10,000 sodium atoms and measured about 8 ...

Researchers have demonstrated that a nanoparticle of 7,000 sodium atoms can act as a wave, creating a record-setting ...

Long before quantum mechanics existed, a scientist developed a powerful way of describing motion by drawing an analogy between particles and light.

The team have pushed the boundaries of quantum mechanics beyond what some thought possible. Now they want to go even further ...

Metal clusters made of thousands of atoms showed quantum interference, offering new insight into how large objects follow quantum rules.

The same phenomenon was later confirmed for neutrons, helium atoms, and even large molecules, making matter-wave diffraction ...

Athought experiment at the heart of an argument between famed physicists Albert Einstein and Niels Bohr in 1927 has finally been made real. Its findin.

A record-breaking experiment shows that a cluster of thousands of atoms can act like a wave as well as a particle ...

The new research demonstrates for the first time that the wave nature of matter persists even at large scales, using massive metallic nanoparticles each about the size of a modern transistor. The ...

Tim Kovachy is in the Department of Physics and Astronomy and at the Center for Fundamental Physics, Northwestern University, Evanston, Illinois 60208, USA. Quantum mechanics predicts that single ...
