Effects of critical fluctuations to stochastic thermodynamic behavior of chemical reaction systems at steady state far from equilibrium

We extend the stochastic thermodynamics of chemical reaction systems to include the critical regime. An explicit theory of stochastic entropy production valid for the fluctuations around non-equilibrium steady state with broadening exponent αā=ā3/4 is presented in this paper. It is shown that the contribution of this critical fluctuations to entropy production tends to the order of Vā1/2 (where V is the volume of the system), mainly consisting of two parts due respectively to the deviations of the distribution from Poissonian behavior and the central limit theorem. Furthermore, it is found that the stochastic average of 2nd order excess entropy production due to internal fluctuations is linked to the entropy production of the critical fluctuations. In this regime of the distribution it is possible to detect the macroscopic stability of chemical reaction systems at steady state by means of a general analysis of the fluctuation behaviour.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
