“…In the analytical aspect, for the existence and multiplicity of bound states and/or standing wave solutions, we refer to [2,3,15,24,[29][30][31]51] and references therein. Particularly, for the case where d = 1, ε = 1, V (x) ≡ 0, λ 1 = −1 and λ 2 = 0 in the choice of F(Φ), the NLDE (1.1) admits explicit soliton solutions [26,40,45,52,56,60,65,66]. In the numerical aspect, many accurate and efficient numerical methods have been proposed and analyzed, such as the finite difference time domain (FDTD) methods [19,46,59], the time-splitting Fourier spectral (TSFP) methods [10,18,39,49] and the Runge-Kutta discontinuous Galerkin methods [48].…”
