Numerical Study of the Pairing Correlation of the t-J Type Models
C. T. Shih, Y. C. Chen, T. K. Lee
We reported that the pair-pair correlation function of the two-dimensional t-J model does not have long-range d-wave superconducting correlations in the interesting parameter range…

Stripe Stability in the Extended t-J Model on Planes and Four-Leg Ladders
T. Tohyama, C. Gazza, C. T. Shih +4
The tendencies to phase-separation and stripe formation of the t-J model on planes and four-leg ladders have been here reexamined including hole hopping terms t', t'' beyond neares…

Low energy excitations of the t-J model in 1D and 2D
R. Eder, Y. C. Chen, H. Q. Lin +3
We present an exact diagonalization study of the low energy singlet and triplet states for both 1D and 2D t-J model. A scan of the parameter ratio J/t shows that for nearly all low…
