Competition between spin exchange and correlated hopping
Y. Saiga, M. Imada
The ground-state phase diagram is numerically studied for an electronic model consisting of the spin exchange term (J) and the correlated hopping term (t_3: the three-site term). T…

Electron Addition Spectrum in the Supersymmetric t-J Model with Inverse-Square Interaction
Mitsuhiro Arikawa, Yasuhiro Saiga, Yoshio Kuramoto
The electron addition spectrum A^+(k,omega) is obtained analytically for the one-dimensional (1D) supersymmetric t-J model with 1/r^2 interaction. The result is obtained first for…
