Kind: research · Impact: low

## In brief

- Kyota Tamano and Keiji Saito study entropy-production fluctuations in homogeneous reversible chemical reactions.
- The authors argue that entropy-production fluctuations are a sharper probe of nonequilibrium criticality than entropy-production response to variations in chemical affinity.
- The work is published in a journal of the American Physical Society, indexed at DOI 10.1103/j2x1-tlq7.

## Why it matters

It offers a way to detect nonequilibrium critical behaviour in chemical reaction networks through fluctuations, which may help physicists and chemists characterise far-from-equilibrium systems.
