On the integrability of the SU(N) Hubbard model
M.J. Martins
TL;DR
This paper constructs explicit intertwiner operators for the monodromy matrices of the SU(N) Hubbard model, leading to new non-additive R-matrices and extending previous results by Shastry.
Contribution
It introduces a new family of non-additive R-matrices for the SU(N) Hubbard model, generalizing earlier integrability results.
Findings
Explicit intertwiner operators for SU(N) Hubbard model
New family of non-additive R-matrices
Generalization of Shastry's earlier work
Abstract
We exhibit explicitly the intertwiner operator for the monodromy matrices of the recent proposed SU(N) Hubbard model [5]. This produces a new family of non-additive R-matrices and generalizes an earlier result by Shastry [2].
