Thanks for your interest. Good question. The short answer is no. However, nearly all the pieces are there since very similar functionality exists. e.g. The energy density might be of interest, see https://qmcpack.readthedocs.io/en/develop/hamiltonianobservable.html#energy-density-estimator and https://doi.org/10.1103/PhysRevB.90.035125
