Last meeting of the Summer: Bosonization II


Journal club talk by Shunsuke Furukawa, continued from Part I.

Furukawa-san discussed 1d spin chains, in particular, the XXZ model. Using the Jordan-Wigner transformation, the spin model was mapped to a system of interacting fermions. The interacting fermions were, in turn, mapped onto a bosonic field theory. Wrapping up, Furukawa-san discussed his own work in mapping out the phase diagram of the XXZ model.

The journal club is adjourned until the summer of 2011, barring exceptionally interesting developments/papers that members might want to discuss.
