This relationship allows one to bound or estimate the energy transfer between a system and its surroundings just by measuring how irreversibly the system behaves. I will show two applications of this result. The first is a technique to detect if a stationary process is consuming energy or not, something of relevance in biophysics. The second is the design of optimal Maxwell&#8217;s demons, i.e., of protocols that, given some information of the state of a system, extract the maximum amount of energy in isothermal processes.<\/div>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The relationship between entropy production and irreversibility can be made quantitative using the Kullbak-Leibler divergence between a process and its time reversal.
