    "abstract": "A theory of BEC interferometry in an unsymmetrical double-well trap has been\ndeveloped for small boson numbers, based on the two-mode approximation. The\nbosons are initially in the lowest mode of a single well trap, which is split\ninto a double well and then recombined. Possible fragmentations into separate\nBEC states in each well during the splitting/recombination process are allowed\nfor. The BEC is treated as a giant spin system, the fragmented states are\neigenstates of S^2 and Sz. Self-consistent sets of equations for the amplitudes\nof the fragmented states and for the two single boson mode functions are\nobtained. The latter are coupled Gross-Pitaevskii equations. Interferometric\neffects may be measured via boson numbers in the first excited mode",
