Entropy production reveals hidden dynamical constraints rather than stochastic disorder

Patrick Romanescu · 2026

Entropy production is often interpreted as a proxy for microscopic disorder or environmental roughness in stochastic systems. We test this interpretation using controlled simulations of overdamped sto…
