Laser light nudges ultracold rubidium atoms, triggering atomic collisions and revealing surprising quantum effects and energy ...

A snapshot of a computer simulation showing how energy density changes over time in the collision of a lead ion with a photon emitted by another lead ion. Disclaimer: AAAS and EurekAlert!

A process of particular interest is what happens when two electrons are transferred to a projectile in a collision and a single photon (a quantum of light) is liberated. The inverse of this process ...
