Universal trade-off between power, efficiency, and constancy in steady-state heat engines
P Pietzonka, U Seifert - Physical review letters, 2018 - APS
Heat engines should ideally have large power output, operate close to Carnot efficiency and
show constancy, ie, exhibit only small fluctuations in this output. For steady-state heat …
