Synopsis

In the presence of interactions, one-dimensional systems behave very differently from their higher-dimensional counterparts. First the pecularities of one dimension will be discussed. We will see that Fermi liquid theory breaks down: the elementary excitations in 1D are not electron-like. Instead the 1D system is a so-called Tomonaga-Luttinger liquid (TLL) with collective excitations (spin & charge density waves). The basic properties of the TLL will be introduced. Then the powerful method of bosonization will be presented. Furthermore, we will discuss the properties of correlation functions and the manifestation of TLL physics in transport properties. We will also have a look at other methods to describe 1D physics and then discuss regimes where the TLL description is not applicable. The latter is an area of active research. Finally, we will address what happens beyond the strictly 1D limit.
