An optical lattice is formed by the interference of counter-propagating laser beams, creating a spatially periodic intensity pattern. The resulting periodic potential may trap neutral atoms via the Stark shift. [1] . Atoms are cooled and congregate at the potential extrema (at maxima for blue-detuned lattices, and minima for red-detuned lattices).

2020年9月29日 · Optical lattices can trap atoms in one-, two- or three-dimensional arrays. The lattice spacing — the distance between neighboring trapping sites — is typically half of the laser light’s wavelength. Scientists can change this angle, or the wavelength, to change the spacing.

2008年6月4日 · An optical lattice, created by interference between two coherent laser beams travelling in opposite directions, is a standing wave with a periodic pattern of dark and bright stripes.

Artificial crystals of light, consisting of hundreds of thousands of optical microtraps, are routinely created by interfering optical laser beams. These so-called optical lattices act as...

An optical lattice is a periodic optical structure created by standing wave laser beams that give rise to the optical potential felt by the atoms in which cooled atoms are trapped (see Fig. 5.16). Ideally, one atom is trapped in each lattice site.

2024年5月29日 · What is an Optical Lattice? An optical lattice is a highly regular, periodic structure formed by the interference of multiple laser beams, creating a pattern of light that can trap and manipulate particles such as atoms, ions, and molecules.

An optical lattice is defined as a perfect periodic potential used to trap atoms, mimicking the behavior of electrons in a crystalline structure in solid-state physics. It is a powerful tool for studying coherence, superfluid properties, quantum transport, and quantum simulations in the context of atomic systems.
