Title: Probability Currents in Out-of-Equilibrium Microwave Circuits

Abstract: 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 in time domain measurements. It allows us to check locally in phase space the violation of detailed balance or the presence of fluctuation loops. We present the data analysis methods and experimental results for several microwave circuits driven by two noise sources in the 4-8GHz frequency range.
