Frenesy: Time-symmetric dynamical activity in nonequilibria

C Maes - Physics Reports, 2020 - Elsevier

specified from an action functional or Lagrangian on spacetime. There, under local detailed …

Mutual linearity of nonequilibrium network currents

PE Harunari, S Dal Cengio, V Lecomte, M Polettini - Physical Review Letters, 2024 - APS
For continuous-time Markov chains and open unimolecular chemical reaction networks, we
prove that any two stationary currents are linearly related upon perturbations of a single …

Dissipation-time uncertainty relation

G Falasco, M Esposito - Physical Review Letters, 2020 - APS
We show that the entropy production rate bounds the rate at which physical processes can
be performed in stochastic systems far from equilibrium. In particular, we prove the …

General Theory of Static Response for Markov Jump Processes

T Aslyamov, M Esposito - Physical Review Letters, 2024 - APS
We consider Markov jump processes on a graph described by a rate matrix that depends on
various control parameters. We derive explicit expressions for the static responses of edge …

Nonequilibrium response for markov jump processes: Exact results and tight bounds

T Aslyamov, M Esposito - Physical Review Letters, 2024 - APS
Generalizing response theory of open systems far from equilibrium is a central quest of
nonequilibrium statistical physics. Using stochastic thermodynamics, we develop an …

Kinetic barrier diagrams to visualize and engineer molecular nonequilibrium systems

E Penocchio, G Ragazzon - Small, 2023 - Wiley Online Library
Molecular nonequilibrium systems hold great promises for the nanotechnology of the future.
Yet, their development is slowed by the absence of an informative representation. Indeed …

Dissipation bounds precision of current response to kinetic perturbations

K Ptaszyński, T Aslyamov, M Esposito - Physical Review Letters, 2024 - APS
The precision of currents in Markov networks is bounded by dissipation via the so-called
thermodynamic uncertainty relation (TUR). In our Letter, we demonstrate a similar inequality …

Information thermodynamics for deterministic chemical reaction networks

E Penocchio, F Avanzini, M Esposito - The Journal of Chemical …, 2022 - pubs.aip.org
Information thermodynamics relates the rate of change of mutual information between two
interacting subsystems to their thermodynamics when the joined system is described by a …

Kinetic asymmetry versus dissipation in the evolution of chemical systems as exemplified by single enzyme chemotaxis

NS Mandal, A Sen, RD Astumian - Journal of the American …, 2023 - ACS Publications
Single enzyme chemotaxis is a phenomenon by which a nonequilibrium spatial distribution
of an enzyme is created and maintained by concentration gradients of the substrate and …
