    Abstract

    Finite temperature properties of a non-Fermi liquid system is analysed based on the temperature dependent Bethe Ansatz equations. We focus mostly on the one-dimensional Hubbard model, as this model is the prototypical model for a non-Fermi liquid system and this is an ideal system to study since it is exactly solvable even at finite temperatures. At finite temperatures spin and charge separation still holds, however the low energy excitations have a spin gap. The properties of this state will be discussed.
