The problem of activated escape in a far-from-equilibrium system is analysed theoretically, numerically and by analogue electronic experiments. The process is shown to occur via optimal fluctuations that are well described, under diverse conditions, in terms of a new physical quantity, the logarithmic susceptibility (LS).
