clock because it (https://www.ptb.de/cms/en/ptb/fachabteilungen/abt4/fb-43/ag-432/strontium-lattice-clock.html) uses a lattice of laser beams to trap atoms - in the case of this clock, strontium - and make the measurement of their movements more precise.
Some of the most accurate clocks on the planet are devices known as optical lattice
In what follows, we study the speed of sound of a two-component pseudospin-[up arrow], [down arrow] fermionic gas loaded on a square optical lattice
with a non-Abelian gauge field A = ([alpha][[sigma].sub.y], - [alpha][[sigma].sub.x]) in the presence of a Zeeman field, where a is independently tunable parameter, and [[sigma].sub.i], i = x, y, z are the Pauli matrices.
This clock holds strontium atoms in a linear array of pancake-shaped traps formed by laser beams, called an optical lattice
. The new 3-D quantum gas clock uses additional lasers to trap atoms along three axes so that the atoms are held in a cubic arrangement.

(Although the installation included an upside-down, back-to-front brain, as sometimes making a cerebral shift physically feels like this!) There came a connecting point in the project where I began drawing imagery that was the equivalent of an optical lattice
for me in the art world, like a crochet doily.
This optical lattice
holds the atoms fast, like eggs in a crate, while gently shaking them.

Rey traps the atoms in an "optical lattice
" of laser lights that allows her to study the atoms and explore their properties.
The aim of this work is to study the effect of competition between cubic and quintic nonlinearities on the existence of bistable solitons with the optical lattice
such as quasicrystal lattices.
