New physics model reveals universal law for entropy production rate

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new method to quantify irreversibility in complex systems by analyzing directed walks. This approach reveals a universal square-root law governing the entropy production rate, independent of specific network topologies or spectral densities. The findings are applicable to multivariate Ornstein-Uhlenbeck dynamics and offer insights into how interaction networks generate entropy. AI

    Directed walks shape a universal square-root law of entropy production rate in nonreciprocal systems

    The entropy production rate (EPR) quantifies irreversibility of a nonequilibrium steady state, yet standard formulas obscure how a complex interaction network generates it. For multivariate Ornstein-Uhlenbeck dynamics on such networks, we express the EPR as a quadratic form in an…
