Bernoulli $$(G'/G)$$ ( G ′ / G ) -expansion method for nonlinear Schrödinger equation under effect of constant potential

In this article, Bernoulli $$(G'/G)$$ -expansion method, which is proposed in this research work, and $$(G'/G)$$ -expansion method are applied to find traveling wave solutions of nonlinear Schrodinger (NLS) equation with constant potential, which include hyperbolic function solution and trigonometric function solution. Dynamic structures of begotten results are illustrated for different potentials in some figures. This proposed method is satisfactory over a wide range of parameters.
