A century-old thought experiment on wave–particle duality is brought into the laboratory using a single trapped atom ...

One of the discoveries that fundamentally distinguished the emerging field of quantum physics from classical physics was the ...

Two landmark quantum experiments have sharpened one of the oldest arguments in modern physics, and the verdict is not kind to Albert Einstein’s instincts about reality. By stripping classic thought ...

The Einstein–de Haas effect, which links the spin of electrons to macroscopic rotation, has now been demonstrated in a ...

For more than a century, modern physics has rested on two towering frameworks that do not quite agree with each other.

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

As physicists search for a theory of quantum gravity, new results show that classical gravity can still interact with quantum fields to allow matter to become entangled. When you purchase through ...

A hundred years ago this week, at the height of the quantum revolution, Austrian physicist Erwin Schrödinger submitted a ...

A real mind-melter: Quantum mechanics is strange, but even for a field of science that regularly defies our conventional understanding of reality, the latest discovery is particularly baffling.

Physicists seem to be obsessed with cats. James Clerk Maxwell, the father of electrodynamics, studied falling feline s to investigate how they turned as they fell. Many physics teachers have used a ...

Electrons are usually described as particles, but in a rare quantum material, that picture completely breaks down ...
