Abstract: Fluctuations limit sensitive measurements, yet at the same time, noise can unravel properties that are concealed in the averaged signal. I will describe our recent studies of electronic shot noise in nanoscale junctions: We derived theoretical expressions and explained measurements of (i) electronic noise that is generated by temperature differences across conductors , and (ii) anomalous-nonlinear electronic shot noise in atomic scale junctions . Furthermore, (iii) I will describe our recent work on the thermodynamic uncertainty relation, a cost-precision trade-off relation, focusing on electronic conductors in nonequilibrium steady state [3-4].
