Photon Shot Noise
A recent theory is reviewed for the shot noise of coherent radiation propagating through a random medium. The Fano factor P/Ī (the ratio of the noise power and the mean transmitted current) is related to the scattering matrix of the medium. This is the optical analogue of Büttiker’s formula for electronic shot noise. Scattering by itself has no effect on the Fano factor, which remains equal to ...
متن کاملSemiclassical theory of shot noise in mesoscopic conductors
A semiclassical theory is developed for time-dependent current fluctuations in mesoscopic conductors. The theory is based on the Boltzmann-Langevin equation for a degenerate electron gas. The low-frequency shot-noise power is related to classical transmission probabilities at the Fermi level. For a disordered conductor with impurity scattering, it is shown how the shot noise crosses over from z...
متن کاملDistribution Function for Shot Noise in Disordered Multichannel Quantum Conductors
We obtain the generating function for shot noise through a disordered multichannel conductor in the zero temperature quantum regime. The distribution of charge transmitted over a fixed time interval is found to be approximately Gaussian.
متن کاملFractional exclusion statistics and shot noise in ballistic conductors
We study the noise properties of ballistic conductors with carriers satisfying fractional exclusion statistics. To test directly the nature of exclusion statistics we found that systems under weakly degenerate conditions should be considered. Typical of these systems is that the chemical potential m is in the thermal range umu ,3kBT . In these conditions the noise properties under current satur...
متن کاملOn the ‘Anomalous’ Resurgence of Shot Noise in Long Conductors
There has been renewed interest in the physics of the so-called ‘crossover’ for current fluctuations in mesoscopic conductors, most recently involving the possibility of its appearance in the passage to the macroscopic limit. Shot noise is normally absent from solid-state conductors in the large, and its anomalous resurgence there has been ascribed to a rich interplay of drift, diffusion, and C...
