Characterization of an Atom Chip with Integrated Coplanar Waveguides

We describe a new neutral atom trapping apparatus at GTRI based on a multilayer atom chip that was designed and fabricated in-house. The bottom conductive layer provides a set of flexible magnetic trap geometries, while the top layer integrates two microwave coplanar waveguides (CPWs) into a gold mirror. Here we present experimental characterization of the atom chip. Future work will focus on guided wave atom interferometry. Similar to the scheme proposed in [1], the near field pattern of the CPWs will be used to manipulate and dress the internal hyperfine states of the rubidium atoms.
