abstract

  • © 2017 American Physical Society. In a recent paper [Alberucci, Jisha, Smyth, and Assanto, Phys. Rev. A 91, 013841 (2015)PLRAAN1050-294710.1103/PhysRevA.91.013841], Alberucci et al. have studied the propagation of bright spatial solitary waves in highly nonlocal media. We find that the main results in that and related papers concerning soliton shape and dynamics, based on the accessible soliton (AS) approximation, are incorrect; the correct results have already been published by others. These and other inconsistencies in the paper follow from the problems in applying the AS approximation in earlier papers by the group that propagated to the later papers. The accessible soliton theory cannot describe accurately the features and dynamics of solitons in highly nonlocal media.
