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…

Low frequency noise in AC biased metallic tunnel junctions
Nicolas Fontaine, Alexandre Dumont, Bertrand Reulet
We study the effect of an AC bias on the low frequency noise, notably with , of metal-insulator-metal tunnel junctions at room temperature. The measurement is performe…

Probability Currents in Out-of-Equilibrium Microwave Circuits
Alexandre Dumont, Pierre Février, Christian Lupien +1
In this work we reconstruct the probability current in phase space of out-of-equilibrium microwave circuits. This is achieved by a statistical analysis of short-time correlations i…
