Floquet scattering matrix approach to the phase noise of a single-electron source in the adiabatic regime

摘要

We give the basic elements of the Floquet scattering matrix approach (Moskalets in Scattering Matrix Approach to Non-stationary Quantum Transport. Imperial College Press, London, 2011) to the dynamic quantum transport in mesoscopic and nanoscopic conductors. We use the scattering formalism to discuss the noise power spectrum of a single electron source working in the adiabatic regime and emitting particles into a chiral electron waveguide. The noise power is found to be quadratic at low frequencies and exponentially suppressed at high frequencies.
