kwant.physics.two_terminal_shotnoise(smatrix)

Compute the shot-noise in a two-terminal setup.

In a two terminal system the shot noise is given by tr((1 - t*t^dagger) * t*t^dagger).

Parameters

smatrix (SMatrix instance) – A two terminal scattering matrix.

Returns

noise – Shot noise measured in noise quanta 2 e^3 |V| / pi hbar.

Return type

float
