On the nonexistence of degenerate phase-shift discrete solitons in a dNLS nonlocal lattice
( Elsevier B.V. , 2018 , Article)We consider a one-dimensional discrete nonlinear Schrdinger (dNLS) model featuring interactions beyond nearest neighbors. We are interested in the existence (or nonexistence) of phase-shift discrete solitons, which correspond ...
