You will need to define SPlus and Sminus for the Hubbard model. Dod you do that?
I thought they were already defined in the "fermion" basis, but I suppose those are particle operators and I'm trying to measure a site property... If I define
<SITEOPERATOR name="Splus" site="x"> cdag_up(x)*c_down(x) </SITEOPERATOR>
<SITEOPERATOR name="Sminus" site="x"> cdag_down(x)*c_up(x) </SITEOPERATOR>
before
<SITEOPERATOR name="Sx" site="x"> 1/2*(Splus(x)+Sminus(x)) </SITEOPERATOR>
I get the expected result. Is this what you meant?
Cheers, Miguel
