Looking through all the NWChem supporting materials, it appears that the only way to run a QM molecular dynamics simulation in NWChem is with plane wave DFT. Am I correct in this conclusion? If not, what are the commands needed to implement PBC with theories like MP2 or DFT?

Yes, your conclusion is correct. Periodic boundary conditions are not available for methods using Gaussian basis sets. Therefore you cannot perform PBC QMD with MP2 or DFT.

Thanks so much for clarifying Edoardo.
