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 …

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 …

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 …

A local–global principle for nonequilibrium steady states

J Calvert, D Randall - Proceedings of the National Academy of Sciences, 2024 - pnas.org
The global steady state of a system in thermal equilibrium exponentially favors
configurations with lesser energy. This principle is a powerful explanation of self …

Thermodynamic constraints on kinetic perturbations of homogeneous driven diffusions

Q Gao, HM Chun, JM Horowitz - Europhysics Letters, 2024 - iopscience.iop.org
We analyze the static response to kinetic perturbations of nonequilibrium steady states that
can be modeled as diffusions. We demonstrate that kinetic response is purely a …

Many biological decision-making processes can be viewed as performing a classification
task over a set of inputs, using various chemical and physical processes as" biological …

[HTML][HTML] Steady-state probabilities for Markov jump processes in terms of powers of the transition rate matrix

D Frezzato - The Journal of Chemical Physics, 2024 - pubs.aip.org
Several types of dynamics at stationarity can be described in terms of a Markov jump
process among a finite number N of representative sites. Before dealing with the dynamical …
