What counts as heat, and what qualifies as useful work when a machine is made from only an atom and particles of light?

For this resonance to be effective, the photon must have a well-defined energy, matching the amount of energy required to put a rubidium atom into an excited state.

"This quantum enhancement of the effective atom size makes collisions on a given lattice site much more likely, increasing the resistivity of the system."

Of course, so much of what’s otherwise known points a finger directly back at Taylor Farms, false-positive atom splitting notwithstanding, and there’s only so much the company can do to deflect.

In 1913, while puzzling over the structure of the atom, Bohr had an idea so exciting that he postponed his honeymoon to write what became a landmark paper.

It was followed by small movements in the positions of atoms within the material, and those structural changes ultimately produced the photoinduced hidden state.

The researchers also used Raman spectroscopy, a laser-based method that shows how atoms are being stretched or compressed.

Chemists use the term "valency" to describe how many "hands" an atom effectively has available to connect with other atoms in a chemical compound.

These regions may be only a few atoms thick, yet they can strongly influence how well the materials on either side work together.

When two or more atoms are bonded, as in water, they form a molecule.
