Extended Hubbard model on a C20 molecule
The electronic correlations on a C20 molecule, as described by an extended Hubbard Hamiltonian with a nearest-neighbor Coulomb interaction of strength V , are studied using quantum Monte Carlo and exact diagonalization methods. For electron-doped C20, it is known that pair binding arising from a purely electronic mechanism is absent within the standard Hubbard model (V = 0). Here we show that t...
متن کاملExactly solvable extended Hubbard model.
One dimensional chiral Hubbard model reduces to the Haldane-Shastry spin chain at half-filling with large but finite on-site energy U . In this talk, we show that the Gutzwiller-Jastrow wavefunctions are the eigen-states of the Hubbard model at U = +∞ at less than half-filling. The full energy spectrum and an infinite set of mutually commuting constants of motion are also given in this limit fo...
متن کاملComplete Solution of a Supersymmetric Extended Hubbard Model
We show that the recently constructed exact solution of the SU(2|2) extended Hub-bard model on a one-dimensional lattice provides a complete set of 4 L eigenstates of the hamiltonian, where L is the length of the lattice.
متن کاملExtended Hubbard model in the presence of a magnetic field
Within the Green’s function and equations of motion formalism it is possible to exactly solve a large class of models useful for the study of strongly correlated systems. Here, we present the exact solution of the one-dimensional extended Hubbard model with on-site U and first nearest neighbor repulsive V interactions in the presence of an external magnetic field h, in the narrow band limit. At...
متن کاملDimerization in a half-filled one-dimensional extended hubbard model.
We use a density-matrix renormalization group method to study quantitatively the phase diagram of a one-dimensional extended Hubbard model at half filling by investigating the correlation functions and structure factors. We confirmed the existence of a novel narrow region with long-range bond-order-wave order that was highly controversial recently between the charge-density-wave phase and Mott ...
