Non-Gaussianity in a quasiclassical electronic circuit

Abstract

We study the non-Gaussian dynamics of a quasiclassical electronic circuit inductively coupled to a mesoscopic conductor. Non-Gaussian noise accompanying the nonequilibrium transport through the conductor significantly modifies the steady-state probability density function (PDF) of the flux in the dissipative circuit. We evaluate the quantum correction of the steady-state PDF by incorporating the quantum fluctuation of the circuit. The inverse formula to infer the statistical properties of the non-Gaussian noise from the steady-state PDF is extended to the classical-quantum crossover regime.
