Plasmas have vary wide range of scientific and practical applications in our modern societies, including astrophysics, nanofabrication, nuclear fusion, sterilization of medical instruments, surface funtionalization, home lighting, etc. 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. The benefits of this research will include, for example, understanding (i) non-equilibrium plasma discharges, which exhibit distinctive properties compared to equilibrium plasmas and which can potentially be exploited in various applications, and (ii) the generation of nanoparticles in magnetized plasmas for applications in astrophysics and nuclear fusion. This research program will be a unique opportunity to train highly qualified personnel in this fascinating field of study.

在我们的现代社会中，血浆具有各种科学和实用应用，包括天体物理学，纳米化，核融合，核融合，医疗仪器的灭菌，表面融合，家庭照明等。等离子体非常复杂，这是由于几个粒子之间的相互作用非常复杂它对包括激光场在内的自我诱导和外部电磁场的高反应性。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。这项研究的好处将包括理解（i）非平衡血浆放电，与平衡等离子体相比具有独特的特性，并且可以在各种应用中利用这些特性，以及（ii）在磁性等离子体中生成磁性等离子体，用于在天体物理学和核融合中应用磁性等离子体。该研究计划将是一个在这个有趣的研究领域中培训高素质人员的独特机会。
