clock because it (https://www.
Some of the most accurate clocks on the planet are devices known as optical lattice
This clock holds strontium atoms in a linear array of pancake-shaped traps formed by laser beams, called an optical lattice
This optical lattice
holds the atoms fast, like eggs in a crate, while gently shaking them.

Clock and its Development"
The physicists built their ytterbium clocks using about 10,000 rare-earth atoms cooled to 10 microkelvin (10 millionths of a degree above absolute zero) and trapped in an optical lattice
made of laser light.

," Nature, Vol.
His team operates a ytterbium optical lattice
clock, one of the latest types of souped-up atomic timepieces.
Topics include electron transport in carbon nanotubes, scattering and pairing in cuprate superconductors, spintronics, single molecule nanomagnets, Fermi-Hubbard physics with atoms in an optical lattice
, first-principles calculations of complex metal-oxide materials, x-ray diffraction microscopy, physics of cellular movements, molecular theories of segmental dynamics and mechanical response in deeply supercooled polymer melts and glasses, rheology of soft materials, the mechanics and statistics of active matter, and dynamics of simple cracks.
One candidate for such a computer is a so-called optical lattice
, in which ultracold atoms are coaxed by strategically placed laser beams into a grid arrangement, rather like eggs in an egg carton.
Recent neutron inelastic scattering measurements at the NCNR have demonstrated a direct relationship between the lowest-frequency transverse optical lattice
vibration and the polar nanostructure, thereby resolving a long-standing discrepancy between prior x-ray and neutron results.
