May 26 to May 28, 2023: I attended 2023 4th International Symposium on Insulation and Discharge Computation for Power Equipment (IDCOMPU 2023) held in Wuhan where I gave an invited talk entitled Particle condensation in 2T non-LTE plasmas of SF6 replacements.
May 12 to May 14, 2023: I attended 2023 IEEE 6th International Electrical and Energy Conference (CIEEC 2023) held in Hefei where I gave an invited talk entitled Design physics-informed neural networks by neural architecture search.
Feb. 03, 2023: We published a paper on how to accelerate plasma simulation based on physics-informed neural networks (PINNs). In this work we proposed a meta-learning method, namely Meta-PINN, to reduce the training time of PINN-based 1D arc simulation. The results indicate that Meta-PINN is an effective method for accelerating the PINN-based 1D arc simulation. This is an invited paper by the special issue of Journal of Physics D: Applied Physics on Data Driven Plasma Science
This paper is now available on Journal of Physics D: Applied Physics.

Aug. 16, 2022: We published a paper on low-temperature plasma simulation based on physics-informed neural networks (PINNs). In this work we proposed two general AI-driven frameworks for low-temperature plasma simulation: Coefficient-Subnet Physics-Informed Neural Network (CS-PINN) and Runge–Kutta Physics-Informed Neural Network (RK-PINN). Based on these two frameworks, we demonstrated preliminary applications in four cases covering plasma kinetic and fluid modeling. The Editors felt that this article is noteworthy, and have chosen it to be promoted as a Featured Article.
This paper is now available on Physics of Fluids.

AI Plasma

Deep learning is a powerful non-linear mapping tool which can express very complex non-linear relationships. We are exploring deep-learning-driven methods for solving the governing equations in plasma modeling by constructing deep neural networks to surrogate the solution of plasma models. This could bring us new and prospective numerical tools for plasma modeling.
