Pair-correlation ansatz for the ground state of interacting bosons in an arbitrary one-dimensional potential

Abstract We derive and describe a very accurate variational scheme for the ground state of the system of a few ultra-cold bosons confined in one-dimensional traps of arbitrary shapes. It is based on assumption that all inter-particle correlations have two-body nature. By construction, the proposed a...
