Experimentalists have mapped the quantum states (band structure) of cold atoms mimicking electrons in a crystal. The technique should allow researchers to study new aspects of electrons in crystals using the atoms as a model.

According to simulations, ultrashort electron pulses could serve as probes of the rapid motion of atomic or molecular electrons, such as the “breathing” of an excited atom or the shuttling of an electron between atoms in a molecule.

Researchers beat the quantum-mechanical fluctuations in an atomic clock by linking many atoms into an entangled quantum state and pushing the fluctuations into a realm that doesn’t influence the time measurement.

In the 1970s and 80s, researchers developed techniques for cooling atoms to very low temperatures using laser light. The work led to improvements in atomic clocks and the observation of a new ultracold state of matter.
