Recent progress in experimental techniques on cold atoms has been stimulating vigorous studies of Bose systems. In cold atom experiments, there is a large degree of freedom in experimental setup design, and time-evolution of the system can be measured directly. These features enable us to study various novel quantum effects in cold atoms. In this article, we discuss junction of Bose condensates confined in one-dimensional potentials theoretically, and introduce a few predictions on the transport phenomena.
