A computational approach to quantum noise in time-dependent nanoelectronic devices
Résumé
We derive simple expressions that relate the noise and correlation properties of a general time-dependent quantum conductor to the wave functions of the system. The formalism provides a practical route for numerical calculations of quantum noise in an externally driven system. We illustrate the approach with numerical calculations of the noise properties associated to a voltage pulse applied on a one-dimensional conductor. The methodology is hower fully general and can be used for a large class of mesoscopic conductors.
