Amplification based on the noise-induced negative differential resistance in a Zener diode
Alexandre Dumont, Bertrand Reulet
A voltage biased Zener diode always exhibit positive differential resistance, thus cannot be used as an element to provide amplification of a signal. We show how to induce negative…

Absence of skewness in the voltage fluctuations of a tunnel junction in the quantum regime
Clovis Farley, Bertrand Reulet
Current fluctuations in a tunnel junction have a remarkable property: On the one hand, their variance corresponds to vacuum fluctuations at low voltage bias , when the electron…

Link between Continuous and Discrete Descriptions of Noise in Nonlinear Resistive Electrical Components
Lucas Désoppi, Bertrand Reulet
We consider the modeling of noise in a nonlinear, classical, resistive electrical component using two models: i) a continuous description based on a stochastic differential equatio…
