Exactly solvable extended Hubbard model.

چکیده
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 for the system.

New Supersymmetric and Exactly Solvable Model of Correlated Electrons.
A new lattice model is presented for correlated electrons on the unrestricted 4-dimensional electronic Hilbert space ⊗n=1C (where L is the lattice length). It is a supersymmetric generalization of the Hubbard model, but differs from the extended Hubbard model proposed by Essler, Korepin and Schoutens. The supersymmetry algebra of the new model is superalgebra gl(2|1). The model contains one sym...

Hubbard model is an important model in the theory of strongly correlated electron systems. In this contribution we introduce this model and the concepts of electron correlation by building on a tight binding model. After enumerating various methods of tackling the Hubbard model, we introduce the numerical method of exact diagonalization in detail. The book keeping and practical implementation ...
متن کاملSuperconductivity in an exactly solvable Hubbard model with bond-charge interaction.
The Hubbard model with an additional bond-charge interaction X is solved exactly in one dimension for the case t = X where t is the hopping amplitude. In this case the number of doubly occupied sites is conserved. In the sector with no double occupations the model reduces to the U = ∞ Hubbard model. In arbitrary dimensions the qualitative form of the phase diagram is obtained. It is shown that ...
متن کاملMutual-exclusion statistics in exactly solvable models in one and higher dimensions at low temperatures.
We study statistical characterization of the many-body states in exactly solvable models with internal degrees of freedom. The models under consideration include the isotropic and anisotropic Heisenberg spin chain, the Hubbard chain, and a model in higher dimensions which exhibits the Mott metal-insulator transition. It is shown that the ground state of these systems is all described by that of...
متن کاملNew exactly solvable model of strongly correlated electrons motivated by high-Tc superconductivity.
We present a new model describing strongly correlated electrons on a general d-dimensional lattice. It differs from the Hubbard model by interactions of nearest neighbours, and it contains the t-J model as a special case. The model naturally describes local electron pairs, which can move coherently at arbitrary momentum. By using an η-pairing mechanism we can construct eigenstates of the hamilt...
