这是一门关于噪声的课程，涵盖了正常金属的一些散射理论，电子噪声相关的Hanbury Brown和Twiss模拟，超导/正常金属结中的噪声相关。用违反Bell不等式的判据描述了NS系统中的纠缠。最后一节是专门的微扰推导噪声在一个特定的一维相关电子系统（Luttinger液体）：边缘态的分数量子霍尔效应，其中准粒子隧穿电流和噪声的比较允许识别准粒子的分数电荷。
This is a course on noise which covers some of the scattering theory for normal metals, Hanbury Brown and Twiss analogs for noise correlations with electrons, noise correlations in superconducting/normal metal junctions. Entanglement in such NS systems is described with a criterion for violating Bell inegalities. The last section is devoted to the perturbative derivation of noise in a particular one dimensional correlated electron system (Luttinger liquid): edge states in the fractional quantum Hall effect, where the comparison of the quasiparticle tunneling current and noise allow to identidy the fractional charge of quasiparticles.
