20 Attoseconds: The Shortest Time Ever Recorded

Over a century ago, Albert Einstein resolved an apparent paradox in the theory of photoemission by describing light as being composed of particles, called photons, rather than waves. Since then, photoemission has bee...

Ultrashort X-Ray Pulses Produce Low Charge States in Nitrogen Molecules

High-charge-state ions in a molecule cause strong Coulomb forces, repulsive forces that try to blow its atoms apart. But the research team's crucial finding was that a way to produce only lower charge states in nitr...

Excited Electrons Leave Atom with Time Delay of 20 Attoseconds

When light is absorbed by atoms, the electrons become excited. If the light particles, so-called photons, carry sufficient energy, the electrons can be ejected from the atom.

Testing the Best-Yet Theory of Nature

The best theory for explaining the subatomic world got its start in 1928 when theorist Paul Dirac combined quantum mechanics with special relativity to explain the behavior of the electron.
