Abstract
We consider a binary mixture of two overlapping Bose-Einstein condensates in two different hyperfine states of 87Rb with nearly indentical magnetic moments. Such a system has been simply realized through application of radio frequency and microwave which drives a two-photon transition between the two states. The nearly identical magnetic moments afford a high degree of spatial overlap, permitting a number of new experiments. We discuss some of the conditions under which the magnetic moments are identical, with particular emphasis placed on the requirements for a time-averaged orbiting potential (TOP) magnetic trap.
