According to the laws of thermodynamics, no heat engine can beat the efficiency of a Carnot cycle. This efficiency traditionally comes with vanishing power output and practical designs, optimized for power, generally achieve far less. Recently, various strategies to obtain Carnot's efficiency at large power were proposed. However, a thermodynamic uncertainty relation implies that steady-state heat engines can operate in this regime only at the cost of large fluctuations that render them…

Optimal Cycles for Low-Dissipation Heat Engines.

It is shown that the optimal strategy is to perform small cycles around a given working point, which can be, thus, chosen optimally, independent of the figure of merit combining power and efficiency that is being maximized.

Fluctuations in heat engines

At the dawn of thermodynamics, Carnot’s constraint on efficiency of heat engines stimulated the formulation of one of the most universal physical principles, the second law of thermodynamics. In

Compatibility of Carnot efficiency with finite power in an underdamped Brownian Carnot cycle in small temperature-difference regime.

The compatibility of the Carnot efficiency and finite power is achieved in the vanishing limit of the relaxation times in the small temperature-difference regime and this result is consistent with a trade-off relation between power and efficiency.

Finite-time thermodynamics of fluctuations in microscopic heat engines

Fluctuations of thermodynamic quantities become non-negligible and play an important role when the system size is small. We develop finite-time thermodynamics of fluctuations in microscopic heat

Correlation-enhanced stability of microscopic cyclic heat engines

For cyclic heat engines operating in a finite cycle period, thermodynamic quantities have intercycle and intracycle correlations. By tuning the driving protocol appropriately, we can get the negative



The power of a critical heat engine

This work focuses on quantum Otto engines and shows that when the working substance is at the verge of a second order phase transition diverging energy fluctuations can enable approaching the Carnot point without sacrificing power.

Diverging, but negligible power at Carnot efficiency: Theory and experiment.

Several models widely used to describe the performance of actual heat engines (HEs) are focused on, providing conditions for attaining the Carnot efficiency in the individual models and explaining practical aspects connected with reaching the Carnots efficiency at large power output.

Universal Trade-Off between Power, Efficiency, and Constancy in Steady-State Heat Engines.

It is proved that out of these three requirements for steady-state heat engines, driven by a constant temperature difference between the two heat baths, only two are compatible.

Carnot cycle at finite power: attainability of maximal efficiency.

The Carnot cycle is generalized so that it is not restricted to slow processes and it is shown that for realistic (i.e., not purposefully designed) engine-bath interactions, the work-optimal engine performing the generalized cycle close to the maximal efficiency has a long cycle time and hence vanishing power.

We study a class of cyclic Brownian heat engines in the framework of finite-time thermodynamics. For infinitely long cycle times, the engine works at the Carnot efficiency limit producing, however,

This work rigorously proves a general trade-off inequality on thermodynamic efficiency and time interval of a cyclic process with quantum heat engines and proves an upper bound on efficiency with the aid of quantum information geometry.

Work and power fluctuations in a critical heat engine.

It is shown that the variance of work output per cycle scales with the same critical exponent as the heat capacity of the working fluid, and that large fluctuations of output work constitute inseparable and dominant element in performance of the macroscopic heat engines close to a critical point.

It is shown that any trade-off measure expressible in terms of efficiency and the ratio of power to its maximum value can be optimized independently of most details of the dynamics and of the coupling to thermal reservoirs.

This work reports an experimental realization of a Carnot engine with a single optically trapped Brownian particle as the working substance and analyses the fluctuations of the finite-time efficiency, showing that the Carnot bound can be surpassed for a small number of non-equilibrium cycles.
