Efficiency At Maximum Power And Optimized Efficiency An Information Theory Approach

We consider a model heat engine which is based on the concepts of information theory,rnattributing irreversible energy dissipation to the information transmission channels. Therndifferent communication channels, classical and quantum, are characterized by their channelrncapacity. We obtain that the model recovers the Carnot principle in the reversiblernlimit and the efficiency at maximum power expression of non reversible thermodynamics.rnWe use optimization criterion to derive the objective function which is a quantity thatrnhelp us for the derivation of optimized efficiency. The criterion predicts the performancernregime of the model heat engine lying between efficiency at maximum power and Carnotrnefficiency. Such regime should be considered as optimum performance regime of the modelrnheat engine. We derive the optimized efficiency, which has the same linear term for therndifferent information channels in the linear response regime, lying between efficiency atrnmaximum power and Carnot efficiency. We expect the optimization method we used tornbe applicable to any finite-time thermodynamic heat engine which meets Hernandez et alrn[1] requirements. Besides it gives clue on the study of high performance thermodynamicrnheat engine
