Dear alps team
i want ti rephrase my question to make it more precise
I have
fermion hubbard model 2 by 2 square plaquette total number of particle = 3 total spin S= 1/2
need ground state energy
which will be plaquette momentum (Pi,0) and (0, Pi) degenerate
The program I wrote is giving plaquette momentum (0,0) and (0,Pi) as ground state, which is wrong as seen in the paper.
My statements are under. Please correct my statements. I tried very much but could not find the correct ground states. It is trivial task as written in paper.
LATTICE_LIBRARY="/temp/ALPS/xml/lattices.xml"; MODEL_LIBRARY="/temp/ALPS/xml/models.xml";
MODEL="fermion Hubbard"; LATTICE="anisotropic square lattice";
L=2; W=2; Sz_total=0.5;
U=0.5;
CONSERVED_QUANTUMNUMBERS="N,Sz" N_total=3
{ t=1.0;}
