Path integral Monte Carlo methods constitute essential tools for the investigation of manybody systems beyond perturbation theory. However, while many static quantities can be computed directly, insight into dynamics is generally limited to an imaginary-time argument. In order to relate such results to experimental data, one needs to perform an analytic continuation back to real time, an ill-posed but well-studied problem. This talk discusses two approaches, which are based on the maximum entropy method and stochastically sampling the trial-space of possible energy spectra. Finally, we will have a look at how this problem was recently dealt with for the case of the uniform electron gas by Dornheim et al.
