As an example, we calculate the dynamics of a higher-order soliton in the mesoscopic case of N=103-104 particles, giving predictions for quantum soliton breather fragmentation. Our results show evidence for gradual fragmentation with formation of multiple single particle condensate states and nonlocal quantum correlations. These results disagree with variational calculations that violate exact dynamical results, due to the use of too few natural modes in variational theories. Methods for going beyond the 1/N expansion will be treated as well.
Such dynamical predictions are testable in BEC experiments using attractive Bose gases with either 7Li or 85Rb condensates.
