摘要: From the governing equation $$-(3+1)$$ -dimensional nonlinear Schrodinger with cubic-quintic-septimal nonlinearities, different diffractions and $${\mathcal {PT}}$$ -symmetric potentials, we obtain two kinds of analytical Gaussian-type light bullet solutions. The septimal term has a strong impact on formation bullets. eigenvalue method direct numerical simulation to solutions imply that stable unstable evolution bullets against white noise attributes coaction dispersion, potential.
