Shot noise in chaotic cavities with an arbitrary number of open channels
D. V. Savin, H. -J. Sommers
Abstract
Using the random matrix approach, we calculate analytically the average shot-noise power in a chaotic cavity at an arbitrary number of propagating modes (channels) in each of the two attached leads. A simple relationship between this quantity, the average conductance and the conductance variance is found. The dependence of the Fano factor on the channel number is considered in detail.
