Plasmas have an incredibly wide range of scientific and practical applications in our modern societies, ranging from astrophysics to nanofabrication, and from nuclear fusion to sterilization of medical instruments, surface functionalization and home lighting. Plasmas are known to be very complex due to the interaction between several particle species, including positively and negatively charged ions, atoms, molecules, radicals, electrons, photons, and eventually nanoparticles, and to its high responsivity to self-induced and external electromagnetic fields, including laser fields. In particular, electrons, due to their small mass, generally have a complicated energy distribution but knowing it is essential to quantify most critical processes taking place in plasmas. For this reason, numerical modeling has always been an intrinsic and essential component of plasma physics. This research program aims at developing further several aspects of numerical plasma physics, some of which are already ongoing and done in collaboration with experimentalists. The planned research relates particularly to time-dependent discharge plasmas and to laser-plasma interaction, at both high and low intensity. The benefits of this research will include for instance the understanding (i) of pulsed plasma discharges, which show different properties with respect to stationary plasmas, (ii) of the growth and transport processes of nanoparticles in magnetized plasmas for applications to surface functionalization, astrophysics and space science, (iii) of ultrashort laser pulse amplification for accessing new ultra-high intensity regimes, and (iv) of laser-induced plasma spectroscopy for mining exploration.**

等离子体在我们的现代社会中具有多种科学和实用的应用，从天体物理学到纳米制作，从核融合到医疗仪器的灭菌，表面功能化和家庭照明。由于几种颗粒物种之间的相互作用，包括积极和负电荷的离子，原子，分子，自由基，电子，光子，最终是纳米颗粒以及其对自我诱导和外部电磁场，包括激光田，包括激光磁场，因此，血浆非常复杂。特别是，由于电子的质量很小，通常具有复杂的能量分布，但是知道在等离子体中量化大多数关键过程至关重要。因此，数值建模一直是血浆物理学的内在和重要组成部分。该研究计划旨在开发数值等离子体物理学的进一步的几个方面，其中一些已经在与实验者合作进行。计划的研究特别涉及时间依赖性的放电等离子体以及高强度和低强度的激光 - 血浆相互作用。这项研究的好处将包括对脉冲血浆放电的理解，这些脉冲血浆排放相对于固定等离子体显示出不同的特性，（ii）（ii）（ii）在磁化等离子体中，纳米粒子在磁化等离子体中的生长和运输过程，用于应用于表面功能化，天体化和太空科学（III）的表面功能化，以访问Ultraser脉冲的新型Ultera-ligh inigh inign lisa-ligh inigh inigh formist（III）。用于采矿探索的血浆光谱。**
