    • To achieve very accurate results for the detail study of the minimum of the entanglement ( p=200 and R=8.35) we have used a basis corresponding to the angular frequency &cross h signω=16 (effective) hartree.

    • In this respect we note that a related abrupt entanglement transition connecting two different sets of bound states should occur even if the structure considered for R smaller than the transition value would simply be a larger single well (the "outer" well), whose width, for example, increases for decreasing R. In this case we would expect though that the entanglement value corresponding to R smaller than the transition point would not be constant and should be less than 0.5, as the corresponding ground-state wave functions would be intermediate between the "factorized" and triplet-type forms
