An optical lattice clock is a type of atomic clock that can be 100 times more accurate than cesium atomic clocks, the current standard for defining "seconds." Its precision is equivalent to an ...

Cesium atomic clocks are really, really good— the best of them have an uncertainty of around a part in 10 16, which is to say when it measures one second, that’s 1.0000000000000000+/-0. ...

Optical lattices have rapidly become a favoured tool of atomic and condensed-matter physicists. These crystals made of light can be used to trap atoms at very low temperatures, creating a workshop ...

Optical lattice clocks could even aid the search for elusive dark matter, Ye said. "Dark matter somehow must interact with ordinary matter, other than just gravitational physics," Ye said.

Optical lattices have also been used to investigate various intriguing aspects of 1D quantum gases. The dimensionality of a macroscopic quantum system can have a large impact on its physical behaviour ...

An optical lattice clock based on strontium atoms achieves unprecedented accuracy. Jul 24, 2024. New super-accurate optical atomic clocks pass critical test. Apr 11, 2019.

Optical lattices are regular arrays of identical energy wells created by criss-crossing laser beams. By injecting ultracold atoms into the energy wells, the lattices can be used to create and study a ...

This week, a paper s put forth an alternative method of standardizing the second, one which reduces the variability between clocks, and has implications for increasingly precise experiments.

Optical lattice clocks could even aid the search for elusive dark matter, Ye said. "Dark matter somehow must interact with ordinary matter, other than just gravitational physics," Ye said.
