Fusion for the one-dimensional Hubbard model
arXiv:1503.04838 · doi:10.1088/1751-8113/48/32/324002
Abstract
We discuss a formulation of the fusion procedure for integrable models which is suitable for application to non-standard R-matrices. It allows for construction of bound state R-matrices for AdS/CFT worldsheet scattering or equivalently for the one-dimensional Hubbard model. We also discuss some peculiar cases that arise in these models.
