In equilibrium thermodynamics, there exists a well-established connection between dynamical fluctuations of a physical system and the dissipation of its energy into an environment. However, few similarly quantitative tools are available for the description of physical systems out of equilibrium. Here, we offer our perspective on the recent development of a new class of inequalities known as thermodynamic uncertainty relations, which have revealed that dissipation constrains current fluctuations… Expand

Unified Thermodynamic Uncertainty Relations in Linear Response.
This work uses linear response theory to deriveThermodynamic uncertainty relations (TURs) in a straightforward and unified way and finds that, for broken time reversal, the bounds on the relative uncertainty are controlled both by dissipation and by a parameter encoding the asymmetry of the Onsager matrix.

Kinetic uncertainty relation
The approach is based on the recent fluctuation response inequality by Dechant and Sasa and can be applied to generic Markov jump systems, which describe a wide class of phenomena and observables, including the irreversible predator-prey dynamics that is used as an illustration. Expand
Finite-time generalization of the thermodynamic uncertainty relation.
It is shown that this relation holds not only for the long-time limit of fluctuations, as described by large deviation theory, but also for fluctuations on arbitrary finite time scales, which facilitates applying the thermodynamic uncertainty relation to single molecule experiments, for which infinite time scales are not accessible.

Thermodynamic uncertainty relations including measurement and feedback.
Thermodynamic uncertainty relations quantify how the signal-to-noise ratio of a given observable is constrained by dissipation and show that any fluctuation relation directly implies a thermodynamic uncertainty relation, considerably increasing their range of applicability. Expand
