Relation between fluctuations and efficiency at maximum power for small heat engines
We study the ratio between the variances of work output and heat input, η^{(2)}, for a class of four-stroke heat engines, which covers various typical cycles. Recent studies on the upper and lower bounds of η^{(2)} are based on the quasistatic limit and the linear response regime, respectively. We e...
