A 1D bosonic many-body system, related to the Bose-Einstein condensation in atomic traps and periodic optical lattices, is described by a coherent state path integral of the grand canonical partition function. Since the interaction is given by a contact potential, as commonly applied in atomic traps
## Abstract The manyβbody Green's function method is applied to the vertical ionization potential of the hydrogen molecule. The ionization potential is calculated iteratively by expanding the selfβenergy part up to third order. The effects of higherβorder correlation corrections and nondiagonal sel
