Information-Theoretic Characterization of Macroscopic Chaos Emerging from the Chemical Master Equation
Kenshin Matsumoto, Shin-ichi Sasa
Open chemical reaction networks exhibit stochastic concentration dynamics at finite system sizes, whereas their macroscopic limit is governed by deterministic rate equations that c…

Singularity of information flow at the Hopf bifurcation point
Kenshin Matsumoto, Shin-ichi Sasa
We investigate the singular behavior of information flow near the Hopf bifurcation point by analyzing the learning rate as a specific measure of information flow. We study the Brus…

Learning rate matrix and information-thermodynamic trade-off relation
Kenshin Matsumoto, Shin-ichi Sasa, Andreas Dechant
Non-equilibrium systems exchange information in addition to energy. In information thermodynamics, the information flow is characterized by the learning rate, which is not invarian…
