An optical lattice is a periodic optical trap produced by interfering light fields. Its periodic potential gives atomic Bloch states and energy bands. For the displayed one-dimensional lattice, the recoil energy is and measures the depth in recoil units.

An optical lattice is a periodic potential created by the interference of multiple laser beams, typically used in the field of atomic, molecular, and optical (AMO) physics. The interference pattern generates a spatially periodic arrangement of light, which can trap neutral atoms or molecules at the minima or maxima of the light intensity. ### Key Features of Optical Lattices: 1. **Formation**: Optical lattices are formed by overlapping laser beams, often in a simple cubic or two-dimensional arrangement.
