Deficiency, Kinetic Invertibility, and Catalysis in Stochastic Chemical Reaction Networks
Shesha Gopal Marehalli Srinivas, Matteo Polettini, Massimiliano Esposito +1
Stochastic chemical processes are described by the chemical master equation satisfying the law of mass-action. We first ask whether the dual master equation, which has the same ste…
Tight uncertainty relations for cycle currents
Matteo Polettini, Gianmaria Falasco, Massimiliano Esposito
Several recent inequalities bound the precision of a current - counting net number of transitions in a system - by a thermodynamic measure of dissipation. However, while currents m…
Effective fluctuation and response theory
Matteo Polettini, Massimiliano Esposito
The response of thermodynamic systems perturbed out of an equilibrium steady-state is described by the reciprocal and the fluctuation-dissipation relations. The so-called fluctuati…
Effective thermodynamics for a marginal observer
Matteo Polettini, Massimiliano Esposito
Thermodynamics is usually formulated on the presumption that the observer has complete information about the system he/she deals with: no parasitic current, exact evaluation of the…
Carnot efficiency at divergent power output
Matteo Polettini, Massimiliano Esposito
The widely debated feasibility of thermodynamic machines achieving Carnot efficiency at finite power has been convincingly dismissed. Yet, the common wisdom that efficiency can onl…
Tightening the uncertainty principle for stochastic currents
M. Polettini, A. Lazarescu, M. Esposito
We connect two recent advances in the stochastic analysis of nonequilibrium systems: the (loose) uncertainty principle for the currents, which states that statistical errors are bo…
Fluctuation-dissipation relations far from equilibrium
Bernhard Altaner, Matteo Polettini, Massimiliano Esposito
Near equilibrium, where all currents of a system vanish on average, the fluctuation-dissipation relation (FDR) connects a current's spontaneous fluctuations with its response to pe…
Conservation laws and symmetries in stochastic thermodynamics
Matteo Polettini, Gregory Bulnes Cuetara, Massimiliano Esposito
Phenomenological nonequilibrium thermodynamics describes how fluxes of conserved quantities such as matter, energy and charge flow from outer reservoirs across a system, and how th…
Dissipation in noisy chemical networks: The role of deficiency
Matteo Polettini, Artur Wachtel, Massimiliano Esposito
We study the effect of intrinsic noise on the thermodynamic balance of complex chemical networks subtending cellular metabolism and gene regulation. A topological network property…
BEST statistics of Markovian fluxes: a tale of Eulerian tours and Fermionic ghosts
Matteo Polettini
We provide an exact expression for the statistics of the fluxes of Markov jump processes at all times, improving on asymptotic results from large deviation theory. The main ingredi…
Transient fluctuation theorems for the currents and initial equilibrium ensembles
Matteo Polettini, Massimiliano Esposito
We prove a transient fluctuation theorem for the currents for continuous-time Markov jump processes with stationary rates, generalizing an asymptotic result by Andrieux and Gaspard…
Cycle/cocycle oblique projections on oriented graphs
Matteo Polettini
It is well known that the edge vector space of an oriented graph can be decomposed in terms of cycles and cocycles (alias cuts, or bonds), and that a basis for the cycle and the co…
Irreversible thermodynamics of open chemical networks I: Emergent cycles and broken conservation laws
Matteo Polettini, Massimiliano Esposito
In this and a companion paper we outline a general framework for the thermodynamic description of open chemical reaction networks, with special regard to metabolic networks regulat…
Nonconvexity of the relative entropy for Markov dynamics: A Fisher information approach
Matteo Polettini, Massimiliano Esposito
We show via counterexamples that relative entropy between the solution of a Markovian master equation and the steady state is not a convex function of time. We thus let down a curt…
Generally covariant state-dependent diffusion
Matteo Polettini
Statistical invariance of Wiener increments under SO(n) rotations provides a notion of gauge transformation of state-dependent Brownian motion. We show that the stochastic dynamics…
