Query: Langevin Simulations of the Half-Filled Cubic Holstein Model   Over the past several years, reliable Quantum Monte Carlo results for the
charge density wave transition temperature $T_{cdw}$ of the half-filled two
dimensional Holstein model in square and honeycomb lattices have become
available for the first time. Exploiting the further development of numerical
methodology, here we present results in three dimensions, which are made
possible through the use of Langevin evolution of the quantum phonon degrees of
freedom. In addition to determining $T_{cdw}$ from the scaling of the charge
correlations, we also examine the nature of charge order at general wave
vectors for different temperatures, couplings, and phonon frequencies, and the
behavior of the spectral function and specific heat.
