  • Microchip ring trap for cold atoms or molecules
    Patent number: 7030370
    Abstract: A microchip ring trap for cold atoms or neutral molecules consists of a particular multi-layer layout of wires on a microchip. These conductive wires may be produced by photolithography on a substrate (e.g. gold on sapphire). There are four wires crucial to the design, essentially a pair of “two-wire waveguides”. These wires are laid out on concentric circles with the inner and outer most wires on lower level of the chip, and the middle pair of wires on the top layer (the chip surface).
