abstract = {<p style="text-align: justify;">We propose an efficient semi-Lagrangian characteristic mapping method for
solving the one+one-dimensional Vlasov-Poisson equations with high precision on a
coarse grid. The flow map is evolved numerically and exponential resolution in linear time is obtained. Global third-order convergence in space and time is shown and
conservation properties are assessed. For benchmarking, we consider linear and nonlinear Landau damping and the two-stream instability. We compare the results with a
Fourier pseudo-spectral method and results from the literature. The extreme fine-scale
resolution features are illustrated showing the method’s capabilities to efficiently treat
filamentation in fusion plasma simulations.</p>},
