Interactions between atoms and light rule the behavior of our physical world, but at the same time, can be extremely complex.

Accurate frequency measurements of a narrow optical clock transition in 171 Yb atoms trapped in an optical lattice establish this system as a serious contender in the quest to develop increasingly ...

Now, in a recent study published in Physical Review Letters, Rey and JILA and NIST Fellow James K. Thompson, along with ...

Physicists at UC Berkeley immobilized small clusters of cesium atoms (pink blobs) in a vertical vacuum chamber, then split each atom into a quantum state in which half of the atom was closer to a ...

Free surfaces have a structure that may differ from the bulk solid and also a different lattice spacing. · "Real" surfaces contain defects such as the ledges, kinks, vacancies and adsorbed atoms as ...

Researchers from the Chinese Academy of Sciences have experimentally demonstrated counterflow superfluidity (CSF) for ...

The chemical composition of a material alone sometimes reveals little about its properties. The decisive factor is often the arrangement of the molecules in the atomic lattice structure or on the ...

An optical lattice clock is a type of atomic clock that ... along with the laser and control system used for trapping and spectroscopy of atoms, was miniaturized. This innovation reduced the ...

The chemical composition of a material alone sometimes reveals little about its properties. The decisive factor is often the arrangement of the molecules in the atomic lattice structure or on the ...

In an optical atomic clock, atoms are irradiated with laser light. If the laser has exactly the right frequency, the atoms change their quantum mechanical state. All external influences on the atoms ...
