Optimal Cycles for Low-Dissipation Heat Engines [PDF]
Physical Review Letters, 2020 We consider the optimization of a finite-time Carnot engine characterized by small dissipations. We bound the power with a simple inequality and show that the optimal strategy is to perform small cycles around a given working point, which can be thus chosen optimally.

Dissipation, correlation and lags in heat engines [PDF]
Journal of Physics A: Mathematical and Theoretical, 2016 By modelling heat engines as driven multi-partite system we show that their dissipation can be expressed in terms of the lag (relative entropy) between the perturbed state of each partition and their equilibrium state, and the correlations that build up among the partitions.
