AI 中文摘要
在弗拉索夫-泊松系统的稳态麦克斯韦平衡框架下，研究了由外部电场产生的平衡粒子分布的优化设计。分析了由此产生的归一化泊松-玻尔兹曼方程，并通过两种互补方法建立了自洽平衡势的存在性和唯一性。基于对归一化非线性源的一致估计的绍德尔不动点论证和基于严格凸自由能泛函的变分方法。在此分析结果基础上，为平衡密度制定了统一的优化设计框架。在同一优化框架内处理谷势、二次跟踪和库尔贝克-莱布勒设计标准。推导了一阶最优性条件，并提出了投影非线性共轭梯度算法来数值求解由此产生的优化问题。
英文摘要
The optimal design of equilibrium particle distributions generated by external electric fields is investigated in the framework of stationary Maxwellian equilibria of the Vlasov-Poisson system. The resulting normalized Poisson-Boltzmann equation is analyzed, and existence and uniqueness of the self-consistent equilibrium potential are established by two complementary approaches. A Schauder fixed-point argument based on uniform estimates for the normalized nonlinear source and a variational approach based on a strictly convex free-energy functional are developed. Building upon these analytical results, a unified optimal design framework is formulated for equilibrium densities. Valley-potential, quadratic tracking, and Kullback-Leibler design criteria are treated within the same optimization framework. First-order optimality conditions are derived, and a projected nonlinear conjugate-gradient algorithm is proposed for the numerical solution of the resulting optimization problems.
