摘要

我们研究了R3\mathbb{R}^3中一个特定椭圆系统正解的存在性,该系统由两个耦合的非线性定态薛定谔方程(NLSEs)组成,即ϵ2Δu+V(x)u=hv(u,v),ϵ2Δv+V(x)v=hu(u,v)-\epsilon^2 \Delta u + V(x) u= h_v(u,v), - \epsilon^2 \Delta v + V(x) v=h_u (u,v)。在关于势函数VV和非线性项hh的某些假设下,我们证明了存在一个解(uϵ,vϵ)(u_\epsilon,v_\epsilon),该解相对于势函数的局部极小点呈指数衰减,且当ϵ0\epsilon \to 0时其能量趋向于集中在这些点附近。我们还根据特定的基态能量估计了该能量。这项工作紧密跟随了 https://doi.org/10.1007/s00526-007-0103-z 中的工作,尽管此处我们考虑了更一般的非线性项,并将 ourselves 限制在区域为R3\mathbb{R}^3的情形。
