DOI: 10.1016/j.ijleo.2019.163322
Abstract: Abstract This paper obtains highly dispersive perturbed bright 1-soliton solution with cubic–quintic–septic nonlinearity by the aid of semi-inverse variational principle. The relation between the parameters, for sustaining solitons, naturally emerge during the course of soliton… read more here.

DOI: 10.1016/j.ijleo.2019.163451
Abstract: Abstract The current work is a generalization of previously reported results on highly dispersive optical solitons with cubic-quintic-septic law of refractive index that was studied with perturbation terms having cubic nonlinearity. The present paper considers… read more here.

Abstract: We study numerically the cubic-quintic-septic Swift-Hohenberg (SH357) equation on bounded one-dimensional domains. Under appropriate conditions stripes with wave number k≈1 bifurcate supercritically from the zero state and form S-shaped branches resulting in bistability between small… read more here.
