There does not exist a general positive correlation between important life-supporting properties and the entropy production rate. The simple reason is that nondissipative and time-symmetric kinetic aspects are also relevant for establishing optimal functioning. In fact those aspects are even crucial in the nonlinear regimes around equilibrium where we find biological processing on mesoscopic scales. We make these claims specific via examples of molecular motors, of circadian cycles and of sensory adaptation, whose performance in some regimes is indeed spoiled by increasing the dissipated power. We use the relation between dissipation and the amount of time-reversal breaking to keep the discussion quantitative also in effective models where the physical entropy production is not clearly identifiable.

A steady nonequilibrium condition for an open system is not only characterized by dissipation, but also by kinetic aspects that quantify the activity in the system and that are nondissipative by definition [16,29,[31][32][33][35][36][37][38][39][40][41][42][43][44][45].…”

“…The experimental test of some fluctuation-dissipation relations has been recently done in Refs. [18,61,137,138] for colloidal particles in toroidal optical traps and in systems subjected to thermal gradients [139,140]. We do not describe here specific experimental results which have already been widely discussed in the abovementioned articles (see also Refs.…”

We summarize in this article the experiments which have been performed to test the theoretical findings in stochastic thermodynamics such as fluctuation theorem, Jarzynski equality, stochastic entropy, out-ofequilibrium fluctuation dissipation theorem, and the generalized first and second laws. We briefly describe experiments on mechanical oscillators, colloids, biological systems, and electric circuits in which the statistical properties of out-of-equilibrium fluctuations have been measured and characterized using the abovementioned tools. We discuss the main findings and drawbacks. Special emphasis is given to the connection between information and thermodynamics. The perspectives and followup of stochastic thermodynamics in future experiments and in practical applications are also discussed.

“…The latter naturally emerges in Markov systems with discrete states as a consequence of temporal coarse-graining; for a more general discussion on delayed and non-delayed contributions in the linear theories see, e.g., Section 3.1.2 in [8]. For other considerations of fluctuation-response relations for thermal perturbations in overdamped diffusions, see [5].…”

We consider stationary driven systems in contact with a thermal equilibrium bath.There is a constant (Joule) heat dissipated from the steady system to the environment as long as all parameters are unchanged. As a natural generalization from equilibrium thermodynamics, the nonequilibrium heat capacity measures the excess in that dissipated heat when the temperature of the thermal bath is changed. To improve experimental accessibility we show how the heat capacity can also be obtained from the response of the instantaneous heat flux to small periodic temperature variations. I. CALORIMETRY OUT OF EQUILIBRIUMStandard thermodynamics deals with equilibrium systems and their energy exchange with the environment as external parameters like the volume or the temperature are changed. If these changes are slow (quasistatic and along equilibria), then the entire scheme simplifies as described by the thermodynamic laws for reversible processes. There heat and entropy get proportional (Clausius heat theorem). As the ability of a specific system to exchange heat and store energy is usually given in terms of the heat capacity (the heat contribution from temperature changes) and the latent heat (when temperature is unchanged), those quantities also yield important information about the internal structure of the equilibrium system. In that way, calorimetry has provided crucial information about microscopic structures and the nature of the physical states.Concerning possible generalizations, the first (and by now more standard) option is to go beyond quasistatic processes and towards a time-resolved thermodynamics. That can be done within the framework of linear response and it naturally leads to a frequency- * Electronic address: netocny@fzu.cz
