An Interpretable Operator-Learning Model for Electric Field Profile Reconstruction in Discharges Based on the EFISH Method

本文提出了一种名为 Decoder-DeepONet (DDON) 的新型可解释算子学习模型，通过实现函数到函数的映射，在电光效应（EFISH）信号反演中显著提升了非平衡等离子体放电电场轮廓的重建精度、泛化能力及对不完整数据的适应性，并利用积分梯度法优化了数据采集窗口。

Imposing quasineutrality on electrostatic plasmas via the Dirac theory of constraints

本文利用狄拉克约束理论，为描述静电等离子体动力学的维拉斯 - 泊松和维拉斯 - 安培系统构建了广义狄拉克括号，通过引入新的广义力项消除电场并强制电荷密度守恒，从而在初始电荷密度为零时实现准中性条件，并通过数值实验验证了该约束对动力学显著的影响。

Bell Plesset Effects on Rayleigh Taylor Instability of Three Dimensional Spherical Geometry

该论文建立了一个包含模式耦合与贝尔 - 普莱塞特（Bell-Plesset）效应的弱非线性多模理论，揭示了在三维球面收缩界面中，非线性耦合优先将能量导向轴对称模式，且贝尔 - 普莱塞特效应使不稳定性增长幅度剧增，为惯性约束聚变和天体物理壳层坍缩提供了新的物理见解。

Effect of front surface engineering on high energy electron, X-ray and heavy ion generation from Relativistic laser interaction with thick high-Z targets

该研究利用 Scarlet 装置探究了不同前表面涂层对厚钽靶与相对论激光相互作用的影响，发现尽管过厚的涂层降低了电子和 X 射线产额，但通过控制涂层密度与厚度可优化能量耦合，且后损伤弹坑分析可作为评估吸收效率的有效手段。

Spatiotemporal Properties of Compressible Magnetohydrodynamic Turbulence from Space Plasma

该研究利用 Cluster 卫星数据及新型多航天器偏振模分解技术，首次定量揭示了地球磁鞘中可压缩磁流体湍流的时空特性，证实慢模存在从弱到强的非线性转变而快模保持弱湍流状态，从而完善了跨模态、跨尺度及强弱湍流机制的可压缩湍流观测特征。
