Thermodynamic Properties of the One-Dimensional Hubbard Model

  • U. Brandt


In the last few years a lot of theoretical work has been done in order to illuminate the properties of the Hubbard Model. This model is one of the simplest which might be able to show the physically important mechanisms in the behaviour of highly correlated electron systems. The motivation for discussion of this model in one dimension is two-fold: first, there exists a series of pseudo-one-dimensional substances, which are suspected of being described, at least quantitatively, by this model (e. g. certain TCNQ-compounds). On the other hand, one may be able to apply well established approximation schemes to the one-dimensional case, and compare them with (approximate or exact) results, which in one dimension can be obtained in other ways.
