Quantum Heat Fluctuations of Single-Particle Sources

Battista, Francesca LU ; Moskalets, M. ; Albert, M. and Samuelsson, Peter LU (2013) In Physical Review Letters 110(12).
Abstract
Optimal single electron sources emit regular streams of particles, displaying no low-frequency charge current noise. Because of the wave packet nature of the emitted particles, the energy is, however, fluctuating, giving rise to heat current noise. We investigate theoretically this quantum source of heat noise for an emitter coupled to an electronic probe in the hot-electron regime. The distribution of temperature and potential fluctuations induced in the probe is shown to provide direct information on the single-particle wave function properties and display strong nonclassical features.
