Shot Noise in Mesoscopic Systems: From Single Particles to Quantum Liquids

Shot noise, originating from the discrete nature of electric charge, is generated by scattering processes. Shot-noise measurements have revealed microscopic charge dynamics in various quantum transport phenomena. In particular, beyond single-particle picture, such proved to be powerful ways investigate electron correlation liquids. Here, we review recent progress shot-noise mesoscopic physics. This summarizes basics theory based on Landauer–Büttiker formalism, measurement techniques used previous studies, and several experiments demonstrating We then discuss three different kinds liquids, namely those formed by, respectively, Kondo effect, fractional Hall superconductivity. Finally, current noise within framework nonequilibrium statistical physics related experiments. hope that this will convey significance a broad range researchers condensed matter
