Universal correlations of one-dimensional electrons at low density
F. Göhmann
We summarize results on the asymptotics of the two-particle Green functions of interacting electrons in one dimension. Below a critical value of the chemical potential the Fermi su…
Correlations in the impenetrable electron gas
F. Göhmann, A. R. Its, V. E. Korepin
We consider non-relativistic electrons in one dimension with infinitely strong repulsive delta function interaction. We calculate the long-time, large-distance asymptotics of field…
Comment on the paper ``Bound States in the One-dimensional Hubbard Model''
F. H. L. Eßler, F. Göhmann, V. E. Korepin
We comment on the preprint cond-mat/9805103 by D. Braak and N. Andrei \cite{BrAn98}. We point out that the ``new'' Bethe Ansatz equations presented in \cite{BrAn98} are identical t…
Time and temperature dependent correlation functions of the 1D impenetrable electron gas
F. Göhmann, A. G. Izergin, V. E. Korepin +1
We consider the one-dimensional delta-interacting electron gas in the case of infinite repulsion. We use determinant representations to study the long time, large distance asymptot…
Fermionic representations of integrable lattice systems
Frank Göhmann, Shuichi Murakami
We develop a general scheme for the use of Fermi operators within the framework of integrable systems. This enables us to read off a fermionic Hamiltonian from a given solution of…
Yangian Symmetry and Quantum Inverse Scattering Method for the One-Dimensional Hubbard Model
Shuichi Murakami, Frank Göhmann
We develop the quantum inverse scattering method for the one-dimensional Hubbard model on the infinite interval at zero density. -matrix and monodromy matrix are obtained as lim…
The Yangian Symmetry of the Hubbard Models with Variable Range Hopping
Frank Göhmann, Vladimir Inozemtsev
We present two pairs of Y() Yangian symmetries for the trigonometric and hyperbolic versions of the Hubbard model with non-nearest-neighbour hopping. In both cases the Yangia…
A note on inverse-square exchange models
Frank Göhmann, Miki Wadati
The su(11) symmetric version of the Haldane-Shastry spin chain is diagonalized by means of a linear transformation. The same transformation applied to the original su(2) model y…
