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…
Spin and charge dynamics of the t-J model at intermediate electron densities: absence of spin-charge separation
R. Eder, Y. Ohta
We present an exact diagonalization study of the dynamical spin and density correlation functions in small clusters of 2D t-J model for intermediate and low electron densities, rho…
Hole pockets in the t-J model
R. Eder, Y. Ohta
We present an exact diagonalization study of the electron momentum distribution n(k) in small clusters of t-J model for different hole concentrations and t/J. Structures in n(k) wh…
Spin bags in the doped t-J model
R. Eder, Y. Ohta
We present a nonperturbative method for deriving a quasiparticle description of the low-energy excitations in the t-J model for strongly correlated electrons. Using the exact diago…
Validity of the rigid band picture for the t-J model
R. Eder, Y. Ohta, T. Shimozato
We present an exact diagonalization study of the doping dependence of the single particle Green's function in 16, 18 and 20 site clusters of t-J model. We find evidence for rigid-b…
Bogoliubov Quasiparticle Excitations in the Two-Dimensional t-J Model
Y. Ohta, T. Shimozato, R. Eder +1
Using a proposed numerical technique for calculating anomalous Green's functions characteristic of superconductivity, we show that the low-lying excitations in a wide parameter and…
