Benzene molecules in a beam containing helium become preferentially aligned like a wheel or a Frisbee. A source of such large, aligned molecules could be useful for chemistry experiments.

Cold atoms can be reflected from a solid surface in the same way that light reflects from a mirror.

A specially prepared Bose-Einstein condensate would produce oppositely directed beams of entangled atoms, which could be used for investigations of entanglement and quantum information theory. In the past only beams of entangled photons have been produced.

A new system can deliver a precisely known number of atoms into a trap with 100% efficiency.

The wavelike surface electrons on certain metal surfaces give rise to an unusual, long-range interatomic force that has now been directly measured.

In a new scheme for controlling a previously unmanageable class of molecules, they are guided along a wire inside a metal tube.

A team of physicists has precisely measured the length and strength of the exceedingly delicate bond formed between two helium atoms.

A high-precision measurement of a gamma-ray wavelength could set the stage for gamma radiation to become the standard ‘meter stick’ for atomic-scale experiments.

According to computer simulations, atomic electrons can be accelerated close to the speed of light without top-of-the-line lasers if a magnetic field is applied along with a medium-energy laser.

Niels Bohr’s famous correspondence principle–that classical and quantum physics must agree under certain conditions–is not correct the way he and many modern textbooks have stated it.

Using a gas of hot rubidium researchers slowed light signals to 90 m/s without using a Bose-Einstein condensate.
