Including a phase in the Bethe equations of the Hubbard model
arXiv:1002.1806 · doi:10.1007/JHEP04(2010)062
Abstract
We compute the Bethe equations of generalized Hubbard models, and study their thermodynamical limit. We argue how they can be connected to the ones found in the context of AdS/CFT correspondence, in particular with the so-called dressing phase problem. We also show how the models can be interpreted, in condensed matter physics, as integrable multi-leg Hubbard models.
