      abstract     = {We use an unbiased, continuous-time quantum Monte Carlo
                      method to address the possibility of a zero-temperature
                      phase without charge-density-wave (CDW) order in the
                      Holstein and, by extension, the Holstein-Hubbard model on
                      the half-filled square lattice. In particular, we present
                      results spanning the whole range of phonon frequencies,
                      allowing us to use the well understood adiabatic and
                      antiadiabatic limits as reference points. For all parameters
                      considered, our data suggest that CDW correlations are
                      stronger than pairing correlations even at very low
                      temperatures. These findings are compatible with a CDW
                      ground state that is also suggested by theoretical
                      arguments.},
