Optical lattice - Wikipedia
An optical lattice is formed by the interference of counter-propagating laser beams, creating a spatially periodic polarization pattern. The resulting periodic potential may trap neutral atoms via the Stark shift. Atoms are cooled and congregate at the potential extrema (at maxima for blue-detuned lattices, and minima … 展开
There are two important parameters of an optical lattice: the potential well depth and the periodicity.
Control of potential depth
The potential experienced … 展开The trapping potential experienced by atoms in an optical dipole trap is weak, generally below 1 mK. Thus atoms must be cooled significantly before loading them into the optical lattice. Cooling techniques used to this end include magneto-optical traps, 展开
The trapping mechanism is via the Stark shift, where off-resonant light causes shifts to an atom's internal structure. The effect of the Stark shift is to create a potential proportional to the … 展开
Once cooled and trapped in an optical lattice, the atoms can be manipulated or left to evolve. Common manipulations involve the "shaking" of the optical lattice by varying the relative … 展开
