Time-reversal symmetry breaking and entropy production are universal features of nonequilibrium phenomena. Despite its importance in the physics of active and living systems, the entropy production of systems with many degrees of freedom has remained of little practical significance because the high dimensionality of their state space makes it difficult to measure. Here we introduce a local measure of entropy production and a numerical protocol to estimate it. We establish a connection between…

Utilizing time-series measurements for entropy production estimation in partially observed systems

This work test different degrees of observed information stemming from coarse-grained time-series trajectory data, and applies several EPR estimators, showing a hierarchy of lower bounds on the total EPR.

Generalized Zurek's bound on the cost of an individual classical or quantum computation

Stochastic thermodynamics is used to derive a generalized version of Zurek's bound from a rigorous Hamiltonian formulation, which applies to all quantum and classical processes, whether noisy or deterministic, and it explicitly captures the dependence on the protocol.

Optimal power extraction from active particles with hidden states

It is argued that the theoretical bounds derived in this work are those against which the performance of realistic active matter engines should be compared.

Quantifying dissipation using fluctuating currents

The determination of entropy production from experimental data is a challenge but a recently introduced theoretical tool, the thermodynamic uncertainty relation, allows one to infer a lower bound on entropy production, and a critical assessment of the practical implementation is provided.

Improved bounds on entropy production in living systems

By reformulating the problem within an optimization framework, the approach is able to infer improved bounds on the rate of entropy production from partial measurements of biological systems, and yields provably optimal estimates given certain measurable transition statistics.

Irreversibility and Biased Ensembles in Active Matter: Insights from Stochastic Thermodynamics

Active systems evade the rules of equilibrium thermodynamics by constantly dissipating energy at the level of their microscopic components. This energy flux stems from the conversion of a fuel,

Time irreversibility in active matter, from micro to macro

Active matter encompasses systems whose individual consituents dissipate energy to exert propelling forces on their environment. This rapidly developing field harbors a dynamical phenomenology with

Efficiency and, in particular, efficiency at maximum power can be discussed systematically beyond the linear response regime for two classes of molecular machines, isothermal ones such as molecular motors, and heat engines such as thermoelectric devices, using a common framework based on a cycle decomposition of entropy production.

Equilibrium Information from Nonequilibrium Measurements in an Experimental Test of Jarzynski's Equality

The implementation and test of Jarzynski's equality provides the first example of its use as a bridge between the statistical mechanics of equilibrium and nonequilibrium systems, and extends the thermodynamic analysis of single molecule manipulation data beyond the context of equilibrium experiments.

Fluctuation-dissipation theorem in nonequilibrium steady states

In equilibrium, the fluctuation-dissipation theorem (FDT) expresses the response of an observable to a small perturbation by a correlation function of this variable with another one that is conjugate

This work considers the situation when the difference of chemical potential between the two species (the driving affinity) can be assumed to be constant, and derives the thermodynamically consistent equations of motion.
