Comparison of the π and ∆ operator approximations for the two-dimensional t-J model


We compare the spectra of the new π operator of the SO(5) theory and the conventional ∆ operator for the two-dimensional t-J model. We also calculate the weight transferred to the two-hole ground state from half-filling by these operators. We find that the spectra of these operators are quite similar and the weight for the π operator is smaller than the… (More)
