Learning time-dependent and integro-differential collision operators from plasma phase space data using differentiable simulators
Diogo D. Carvalho, Luis O. Silva, E. Paulo Alves
Collisional and stochastic wave-particle dynamics in plasmas far from equilibrium are complex, temporally evolving, stochastic processes which are challenging to model. In this wor…

Learning the dynamics of a one-dimensional plasma model with graph neural networks
Diogo D Carvalho, Diogo R Ferreira, Luis O Silva
We explore the possibility of fully replacing a plasma physics kinetic simulator with a graph neural network-based simulator. We focus on this class of surrogate models given the s…
