摘要:

该文研究了描述等离子体中拉曼放大模型的一类非线性 Schrödinger 方程组 (含三波相互作用) 在非聚焦情形下的驻波解. 在空间维数$ N=4$ 的情形下, 运用变分方法和紧性分析建立了该方程组基态解的存在性和非存在性. 进一步, 还刻画了基态的质量同步渐近行为, 并建立了其与 Thomas-Fermi 极限之间的精确对应关系. 该工作是在文献 [Forcella L, Luo X, Yang T, et al. arXiv: 2210.07643] 基础上对高维情形的进一步研究与推广.

关键词: NLS 方程组, 驻波, 基态解, 渐近行为

Abstract:

This paper studies standing wave solutions for a class of nonlinear Schrödinger system (involving three-wave interactions) that describe the Raman amplification model in plasmas within the non-focusing regime. For spatial dimension $N=4$, the existence and nonexistence of ground state solutions are established by means of variational methods and compactness analysis. Furthermore, the asymptotic behavior of the ground states under synchronized mass variations is characterized, and a precise correspondence with the Thomas-Fermi limit is established. This work extends and generalizes the results of [Forcella L, Luo X, Yang T, et al. arXiv: 2210.07643] to higher dimensions.

Key words: NLS system, standing waves, ground state solution, asymptotic behavior
