Have you tried setting the Nup_total and Ndown_total ? The quantum numbers are Nup and Ndown

Dear Sir
I am not able to calculate the energy states for the fermionic hubbard model for 2 by 2 plaquette for 3 particles total spin S=0.5
Actually for 3 particles the total spin comes out to be 1.5 as measured by MEASURE_AVERAGE[Magnetization]="Sz" command
I need the energies for the model described above. please write a program for me.
I am very upset as I tried all the combinations I think and get the same input. Thats why this is third mail from me in this day.
