model as effective Hamiltonian for generalized Hubbard models with broken -symmetry
G. Albertini, V. E. Korepin, A. Schadschneider
We consider the limit of strong Coulomb attraction for generalized Hubbard models with -symmetry. In this limit these models are equivalent to the ferromagnetic spin-1/2 Heisenb…
Exactly Solvable Models of Strongly Correlated Electrons
V. E. Korepin, F. H. L. Essler
This is a reprint volume devoted to exact solutions of models of strongly correlated electrons in one spatial dimension by means of the Bethe Ansatz.
Determinant Representations for Correlation Functions of Spin-1/2 XXX and XXZ Heisenberg Magnets
F. H. L. Essler, H. Frahm, A. G. Izergin +1
We consider correlation functions of the spin-$\half$ XXX and XXZ Heisenberg chains in a magnetic field. Starting from the algebraic Bethe Ansatz we derive representations for vari…
-pairing as a mechanism of superconductivity in models of strongly correlated electrons
Jan de Boer, Vladimir E. Korepin, Andreas Schadschneider
We consider extended versions of the Hubbard model which contain additional interactions between nearest neighbours. In this letter we show that a large class of these models has a…
Differential equation for a correlation function of the spin- Heisenberg chain
Holger Frahm, Alexander R. Its, Vladimir E. Korepin
We consider the probability to find a string of adjacent parallel spins in the antiferromagnetic ground state of the model (in a magnetic field). We derive a system of integro-…
Correlation Function of the Spin-1/2 XXX Antiferromagnet
Vladimir E. Korepin, Anatoli G. Izergin, Fabian H. L. Essler +1
We consider a special correlation function in the isotropic spin-$\half$ Heisenberg antiferromagnet. It is the probability of finding a ferromagnetic string of (adjacent) spins in…
