Abstract

We have studied the effects of electron-electron interaction on the 2D localized modes of a soliton using the two-dimensional model that includes the bond-bending term and pinning effects in the photoexcited samples. The result shows that seven localized modes always exist, but the frequencies slightly move for different parameter λ and their localization are strengthened.
