In the past three decades, the field of stochastic thermodynamics has been formulated and
highly developed. Stochastic thermodynamics extends the framework of thermodynamics …

Thermodynamic performance analysis of microscopic Feynman's engine has always been a
hot topic, since it can reveal the operating mechanism of the system and give out the …

In this paper, we analyze the advanced Feynman's mechanism from the well-known
Feynman's Lectures on Physics, under the maximum power output, maximum efficient …

Technology that makes use of waste heat or low-grade energy is important for addressing
worldwide energy security concerns. This study proposes the application of a natural …

Based on a variational expression for the steady-state entropy production rate in
overdamped Langevin dynamics, we derive concrete upper bounds on the entropy …

Effective utilization of unused heat below 200° C is a vital issue for a zero-emission society.
Here, we propose a two-phase Büttiker–Landauer (BL) ratchet pump using nucleate boiling …

We investigate a class of nonequilibrium media described by Langevin dynamics that
satisfies the local detailed balance. For the effective dynamics of a probe immersed in the …

The difference between the zero-mass limit of the heat exchanged with a thermal reservoir,
and its value as determined from overdamped dynamics, is termedheat leakage'orhidden …
