Numerical Study of the Incommensurate Phase in Spin-Peierls Systems
A. E. Feiguin, J. A. Riera, A. Dobry +1
We analyze several properties of the lattice solitons in the incommensurate phase of spin-Peierls systems using exact diagonalization and quantum Monte Carlo. These systems are mod…
Study of the magnetic susceptibility in the spin-Peierls system CuGeO
Jose Riera, Ariel Dobry
We study numerically, using a one-dimensional Heisenberg model, the spin-Peierls transition in the linear Cu spin-1/2 chains in the inorganic compound CuGeO which has be…
Polaron Formation in the Three-Band Peierls-Hubbard Model for Cuprate Superconductors
J. Lorenzana, A. Dobry
Exact diagonalization calculations show a continuous transition from delocalized to small polaron behavior as a function of intersite electron-lattice coupling. A transition, found…
Polaronic Self-Localization Effects in the Three Band Peierls Hubbard Model
A. Dobry, A. Greco, J. Lorenzana +1
We have studied the three-band Peierls-Hubbard model describing the Cu-O layers in high-T superconductors by using Lanczos diagonalization and assuming infinite mass for the io…
