Comment on “A new integrable two-parameter model of strongly correlated electrons in one dimension”

Accepted: 19 April 1996
In a recent letter [Bariev R. Z., Klümper A. and Zittartz J., Europhys. Lett. bf 32, 1995, 85.], a Hamiltonian for a system of correlated electrons in one-dimension was presented. (...) The objective of this comment is to make it apparent that the above model, with appropriate modifications, is the quantum analogue of the supersymmetric U model of ref..  Bracken A. J., Gould M. D., Links J. R. and Zhang Y.-Z., Phys. Rev. Lett. 74, 1994, 2768.
