Description

This work proposes the use of generative models and differentiable simulations to search for smooth equilibrium phase space distributions in arbitrary external fields. The model parameters are optimized using a two-term loss function: one term suppresses period-to-period fluctuations in the distribution function, while a second term pulls the distribution toward some target value, e.g. to encourage smoothness. As an initial demonstration of this approach, we search for a four-dimensional equilibrium in a simple linear focusing lattice. We also discuss possible extensions to more complicated lattices and higher-dimensional phase spaces.
