A Minimal Thermodynamically Consistent Chemical Oscillator
Benedikt Remlein, Luca Monari, Beatrice Bartolomei +3
Inspired by the chemical reaction network considered as the smallest system featuring a Hopf bifurcation and its reversible extension, we introduce an even more minimal reaction ne…
Identifying Non-Ideal Reaction-Diffusion Systems Unable to Maintain Diffusion Out-of-Equilibrium
Francesco Avanzini, Timur Aslyamov, Massimiliano Esposito
We develop a general method, based on the construction of a kinetic potential serving as a Lyapunov function, to establish when diffusion necessarily equilibrates in non-ideal reac…
Dynamical Fluctuation-Response Relations
Timur Aslyamov, Massimiliano Esposito
We derive exact dynamical fluctuation-response relations (FRRs) for time-integrated observables of any nonautonomous Markov jump process. The finite-time covariance splits into an…
Emergence of Open Chemical Reaction Network Thermodynamics within Closed Systems
Benedikt Remlein, Massimiliano Esposito, Francesco Avanzini
We address a fundamental question: under which conditions do the dynamics and thermodynamics of open chemical reaction networks (CRNs), grounded on the notion of idealized chemosta…
Coarse Graining Photo-Isomerization Reactions: Thermodynamic Consistency and Implications for Molecular Ratchets
Francesco Avanzini, Massimiliano Esposito, Emanuele Penocchio
We formulate thermodynamically consistent coarse-graining procedures for molecular systems undergoing thermally and photo-induced transitions: starting from elementary vibronic tra…
What is a chemostat? Insights from hybrid dynamics and stochastic thermodynamics
Benedikt Remlein, Massimiliano Esposito, Francesco Avanzini
At the microscopic scale, open chemical reaction networks are described by stochastic reactions that follow mass-action kinetics and are coupled to chemostats. We show that closed…
