Abstract
The modulational instability of Gross-Pitaevskii-type equations in 1+1 dimensions was investigated. The theoretical predictions for modulational instability were verified by the numerical experiments. The results showed that the resulting growth term is constant for specific forms of temporal dependence of the prefactor of the harmonic potential.
