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

Katrina Hibberd

Published Jun 10, 1996• 1 citation
Publisher

Abstract

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.[2]. [2] Bracken A. J., Gould M. D., Links J. R. and Zhang Y.-Z., Phys. Rev. Lett. 74 , 1994, 2768.

A New Integrable Two-Parameter Model of Strongly Correlated Electrons in One Dimension

R. Z Bariev, A Klümper, J Zittartz

A new one-dimensional fermion model depending on two independent interaction parameters is formulated and solved exactly by the Bethe-ansatz method. The Hamiltonian of the model contains the Hubbard interaction and correlated hopping as well as pair hopping terms. The density-density and pair correlations are calculated which manifest superconducting properties in certain regimes of the phase diagram.

Comment on "A new exactly solvable quantum model in $N$ dimensions" [Phys. Lett. A 375(2011)1431, arXiv:1007.1335]

B. L. Moreno Ley, Shi‐Hai Dong

We pinpoint that the work about "a new exactly solvable quantum model in $N$ dimensions" by Ballesteros et al. [Phys. Lett. A {\bf 375} (2011) 1431, arXiv:1007.1335] is not a new exactly solvable quantum model since the flaw of the position-dependent mass Hamiltonian proposed by them makes it less valuable in physics.
