    • Since in the VMC calculation, the average of H is calculated without the chemical potential term, whereas the ground state energy in the HFA is calculated including the chemical potential, to the energy given in ( refeq:Eg) a constant u Ne has to be added to obtain the ground state energy at a fixed number of particles. At half filling, this constant equals NsU/2. In this way, the ground state energy at half filling goes to zero in the limit of infinitely large U.

    • Table III in Ref. onlineciteGAn contains a printing error: the ground state energy using the Gutzwiller wave function (EGWF) for the commensurate phase (GWF CM) for U/t = 10 should be -56.46 instead of -54.46.
