Robin— It’s the last sentence in the introduction that is pertinent. It makes the point that the BEC Can be described by a wave function as if it were a single particle. The wave function would include spacial parameters relative to its charge center or with respect to its axis in a magnetic field.
You suggest that a coherent system state as described by a wave function does include a specification of probable . relative location of charge centers and/or magnetic dipole centers. What are the parameters of the system state that you believe the paper considers are pertinent?
