非线性Schroedinger方程中孤子的动力学性质

On the Dynamics of solitons in the nonlinear Schroedinger equation

Vieri Benci, Marco Ghimenti, Anna Maria Micheletti

摘要:

研究了方程i((\partial)/(\partialt))=-(1/(2 m))Δ ε +(1/2)W_{ε} '(ε)+V(x)ε的孤子解的行为,其中W_{ε} '是一个合适的非线性项,当ε=0时,它是奇异的.我们利用强非线性得到了孤子的存在性、形状、稳定性和动力学性质的结果。本文的主要结果(定理1)表明,对于ε \to 0,我们的孤子轨道接近于势V(x)中经典粒子的轨道.

英文摘要:

We study the behavior of the soliton solutions of the equation i((\partialψ)/(\partialt))=-(1/(2m))Δψ+(1/2)W_{ε}'(ψ)+V(x)ψ where W_{ε}' is a suitable nonlinear term which is singular for ε=0. We use the "strong" nonlinearity to obtain results on existence, shape, stability and dynamics of the soliton. The main result of this paper (Theorem 1) shows that for ε\to0 the orbit of our soliton approaches the orbit of a classical particle in a potential V(x).
