After the publication of this Letter, the authors realized a mistake in the analysis of the linear response theory. On page 3, left column, we stated, “Retaining the terms up to the quadratic orders in Erod and taking the flat-ribbon limit h/w?0, we arrive at the Euler-Lagrange equations for ? and ? as ?'=?/R and ?'' '' - ( G - 2 ) ? '' / R 2 + ? / R 4 = 0 , where G=(1+?)/2.” The correct form of the Euler-Lagrange equation for ?(s) should be the following: (Formula Presented). he quadratic term -A2?2/(2R2) was incorrectly omitted in the expansion of elastic energy Erod . Including that term leads to a modified third term (1-G)?/R4 in the left-hand side of Eq. (1). We updated the Supplemental Material, which now provides the correct analytical solution of Eq. (1) for arbitrary G. In the G?0 limit, the solution correctly reduces to Eq. (2) defined in this Letter. All other equations and analyses are correct; hence, the conclusions remain unchanged.

Stochastic Mean Field Model of Heat Engine partitioned by Fluctuating Piston

　View Summary

We propose a stochastic mean field model of heat engine partitioned by a<br />
finite-mass piston. The time evolution equations for the density and the<br />
temperature of the enclosed gas are proposed, taking into account the<br />
stochastic equation of motion of the piston, and the energy conservation for<br />
the gas. Though the heat cycle consisting of finite-time heating and cooling<br />
processes is under strong non-equilibrium situations, i. e., the ratio of<br />
temperatures of two reservoirs is large, we analyze the efficiency and the<br />
power, and derive the semi-analytical expression for the efficiency. We find<br />
that the obtained efficiency at the maximum power operation is close to the<br />
Chambadal-Novikov-Curzon-Ahlborn (CNCA) efficiency, if the piston is<br />
sufficiently heavy and elastic for collisions with particles, even when the<br />
system is far from equilibrium. However, the extra heat due to the finiteness<br />
of the piston-mass or its inelasticity lowers the efficiency from the CNCA<br />
efficiency. The results of our stochastic mean field model are consistent with<br />
those for our event driven molecular dynamics simulation.
