报告摘要： In these lectures, we will consider systems in which the motion of electrons is confined to one dimension (1D). In these so-called quantum wires electron-electron interaction effects play an important role because the restricted dimensions enhance the scattering between the electrons and completely destroy the quasi-particle picture. New density wave excitations appear that are described by bosonic operators. Here we will develop this bosonic description, following a “pedestrian” approach which does not require any previous knowledge in field theory methods. These notes therefore serve as a detailed introduction into bosonization by carefully deriving the most fundamental formulas. Details can be found in following notes: https://www.physik.uni-kl.de/eggert/eggert-bos.pdf
