Universal Trade-Off Relation between Power and Efficiency for Heat Engines
Universal Trade-Off Relation between Power and Efficiency for Heat Engines
For a general thermodynamic system described as a Markov process, we prove a general lower bound for dissipation in terms of the square of the heat current, thus establishing that nonvanishing current inevitably implies dissipation. This leads to a universal trade-off relation between efficiency and power, with which we rigorously …
