First-Order Lagrangians and Path-Integral Quantization in the t-J Model
A. Foussats, A. Greco, O. S. Zandron
By using the supersymmetric version of the Faddeev-Jackiw symplectic formalism, a family of first-order constrained Lagrangians for the t-J model is found. In this approach the Hub…

Stability of correlated electronic systems under the influence of the electron-phonon interaction
A. Greco, A. Dobry
We have used an exact diagonalization technique to study the stability of the -Holstein and Hubbard-Holstein models under the influence of the electron-phonon interaction. Pre…

Exact diagonalization study of the two-dimensional t-J-Holstein model
A. Dobry, A. Greco, S. Koval +1
We study by exact diagonalization the two-dimensional t-J-Holstein model near quarter filling by retaining only few phonon modes in momentum space. This truncation allows us to inc…
