[ALPS-users] Sx in 1D Hubbard Model

Hello all. As a test case for Alps 2, we are running fulldiag for a 1D Hubbard model with only three lattice sites, res = pyalps.runApplication('fulldiag',input_file,writexml=True) data = pyalps.loadEigenstateMeasurements(pyalps.getResultFiles(prefix='parm1')) and are measuring 'MEASURE_CORRELATIONS[Sx Sx]' : "Sx:Sx", 'MEASURE_CORRELATIONS[Sz Sz]' : "Sz:Sz", 'MEASURE_CORRELATIONS[NupNdw]' : "Nup:Ndown", 'MEASURE_CORRELATIONS[NupNup]' : "Nup:Nup", and everything seems to check out fine, except of <Sx Sx>. We see that the site operator Sx is correctly defined from Splus and Sminus, but is this the way to use it in the measurements? Cheers, Miguel
