Thermodynamic and Stoichiometric Laws Ruling the Fates of Growing Systems
Atsushi Kamimura, Yuki Sughiyama, Tetsuya J. Kobayashi
We delve into growing open chemical reaction systems (CRSs) characterized by autocatalytic reactions within a variable volume, which changes in response to these reactions. Underst…
The Geometry of Thermodynamic Uncertainty Relations in Chemical Reaction Networks
Dimitri Loutchko, Yuki Sughiyama, Tetsuya J. Kobayashi
Recently, Hessian geometry - an extension of information geometry - has emerged as a framework to naturally connect the geometries appearing in the theory of chemical reaction netw…
Riemannian Geometry of Optimal Driving and Thermodynamic Length and its Application to Chemical Reaction Networks
Dimitri Loutchko, Yuki Sughiyama, Tetsuya J. Kobayashi
It is known that the trajectory of an endoreversibly driven system with minimal dissipation is a geodesic on the equilibrium state space. Thereby, the state space is equipped with…
Chemical Thermodynamics for Growing Systems
Yuki Sughiyama, Atsushi Kamimura, Dimitri Loutchko +1
We consider growing open chemical reaction systems (CRSs), in which autocatalytic chemical reactions are encapsulated in a finite volume and its size can change in conjunction with…
A Hessian Geometric Structure of Chemical Thermodynamic Systems with Stoichiometric Constraints
Yuki Sughiyama, Dimitri Loutchko, Atsushi Kamimura +1
We establish a Hessian geometric structure in chemical thermodynamics which describes chemical reaction networks (CRNs) with equilibrium states. In our setup, the ideal gas assumpt…
Fitness response relation of a multi-type age-structured population dynamics
Yuki Sughiyama, So Nakashima, Tetsuya J. Kobayashi
We construct a pathwise formulation for a multi-type age-structured population dynamics, which involves an age-dependent cell replication and transition of gene- or phenotypes. By…
The explicit form of the rate function for semi-Markov processes and its contractions
Yuki Sughiyama, Testuya J. Kobayashi
We derive the explicit form of the rate function for semi-Markov processes. Here, the "random time change trick" plays an essential role. Also, by exploiting the contraction princi…
Discreteness-induced transitions in multi-body reaction systems
Yohei Saito, Yuki Sughiyama, Kunihiko Kaneko +1
A decrease in system size can induce qualitatively different behavior compared to the macroscopic behavior of the corresponding large-size system. The mechanisms of this transition…
Steady state thermodynamics in population dynamics
Yuki Sughiyama, Tetsuya J. Kobayashi
We report that population dynamics in fluctuating environment accompanies mathematically equivalent structure to steady state thermodynamics. By employing the structure, population…
Variational Principle in Langevin Processes
Yuki Sughiyama, Masayuki Ohzeki
The recent work, Nemoto and Sasa [Phys. Rev. E, 83: 030105(R) (2011)], has shown that large deviations of the current characterizing a nonequilibrium system are obtained by observi…
Nonequilibrium Work Relation in Macroscopic System
Yuki Sughiyama, Masayuki Ohzeki
We reconsider a well-known relationship between the fluctuation theorem and the second law of thermodynamics by evaluating a probability measure-valued process. In order to establi…
Macroscopic proof of the Jarzynski-Wojcik fluctuation theorem for heat exchange
Yuki Sughiyama, Sumiyoshi Abe
In a recent work, Jarzynski and Wojcik (2004 Phys. Rev. Lett. 92, 230602) have shown by using the properties of Hamiltonian dynamics and a statistical mechanical consideration that…
Fluctuation theorem for the renormalized entropy change in the strongly nonlinear nonequilibrium regime
Yuki Sughiyama, Sumiyoshi Abe
Generalizing a recent work [T. Taniguchi and E. G. D. Cohen, J. Stat. Phys. 126, 1 (2006)] that was based on the Onsager-Machlup theory, a nonlinear relaxation process is considere…
