General memory kernels and further corrections to the variational path integral approach for the Bogoliubov-Fröhlich Hamiltonian

Timour Ichmoukhamedov, Jacques Tempere

The celebrated variational path integral approach to the polaron problem shows remarkable discrepancies with diagrammatic Monte Carlo for the Bogoliubov-Fröhlich Hamiltonian which…
