Query: Canonical and Grand Canonical Ensemble Expectation Values from Quantum
  Monte Carlo Simulations   We show how canonical ensemble expectation values can be extracted from
quantum Monte Carlo simulations in the grand canonical ensemble. In order to
obtain results for all particle sectors, a modest number of grand canonical
simulations must be performed, each at a different chemical potential. From the
canonical ensemble results, grand canonical expectation values can be extracted
as a continuous function of the chemical potential. Results are presented from
the application of this method to the two-dimensional Hubbard model.
