Abstract: We study the scattering of solitons from an impurity in the framework of the discrete nonlinear Schrödinger equation with a saturable nonlinearity. We show that this model displays a complex scenario compared to the same equation with cubic nonlinearity. For instance, even considering a single value of the soliton speed and frequency, one can generally observe the existence of a reflected and a transmitted soliton after the interaction between the incoming soliton and the impurity, and that in the case of an attractive impurity, a trapped soliton can coexist with the reflected and transmitted ones.

Abstract: This document is a correction notice for an article titled "Electrostatic wave interaction via asymmetric vector solitons as precursor to rogue wave formation in non-Maxwellian plasmas" published in Scientific Reports. The correction addresses an error in the analytical expression in the section Modulational instability: compatibility condition and growth rate, where "K4" was omitted. The corrected version of the article is now available. The authors of the article are N. Lazarides, Giorgos P. Veldes, D. J. Frantzeskakis, and Ioannis Kourakis. [Extracted from the article]
