Thermodynamics of growth in chemical reaction networks — •Shesha Gopal Marehalli Srinivas, Francesco Avanzini, and Massimiliano Esposito — Complex Systems and Statistical Mechanics, Department of Physics and Materials Science, University of Luxembourg, L-1511 Luxembourg

Open chemical reaction networks show a variety of complex dynamical behaviour such as chemical waves, oscillations, chaotic dynamics, multistability, and so on. Progress in stochastic thermodynamics has enabled us to identify the energetic costs of these phenomena. However, very little attention has been paid to chemical growth. We will identify the necessary conditions under which open homogeneous CRNs evolving with mass action kinetics show asymptotic growth. Our main results show that growth with nonequilibrium abundances requires nonlinear CRNs with the influx of at least one species from the surrounding. Linear CRNs, on the other hand, can only grow with equilibrium abundances. Our results illustrate the important interplay between topology and the chemostatting procedure in determining the asymptotic dynamics of CRNs.
