Precision measurement with an optical Josephson junction
Abstract
We study a new type of Josephson device, the so-called "optical Josephson junction" as proposed in Phys. Rev. Lett. 95, 170402 (2005). Two condensates are optically coupled through a waveguide by a pair of Bragg beams. This optical Josephson junction is analogous to the usual Josephson junction of two condensates weakly coupled via tunneling. We discuss the use of this optical Josephson junction, for making precision measurements.
