The thermodynamic uncertainty relation expresses a seemingly universal trade-off between the cost for driving an autonomous system and precision in any output observable. It has so far been proven for discrete systems and for overdamped Brownian motion. Its validity for the more general class of underdamped Brownian motion, where inertia is relevant, was conjectured based on numerical evidence. We now disprove this conjecture by constructing a counterexample. Its design is inspired by a…

Universal Thermodynamic Uncertainty Relation in Non-Equilibrium Dynamics
We derive a universal thermodynamic uncertainty relation (TUR) that applies to an arbitrary observable in a general Markovian system. The generality of our result allows us to make two findings: (1)
Bounds on the precision of currents in underdamped Langevin dynamics
We derive bounds on the precision of fluctuating currents, which are valid for the steady state of underdamped Langevin dynamics. These bounds provide a generalization of the overdamped thermodynamic
Coherence of oscillations in the weak-noise limit
In a noisy environment, oscillations loose their coherence which can be characterized by a quality factor. We determine this quality factor for oscillations arising from a driven Fokker-Planck
Thermodynamic Uncertainty Relation in Interacting Many-Body Systems
The thermodynamic uncertainty relation (TUR) has been well studied for systems with few degrees of freedom. While, in principle, the TUR holds for more complex systems with many interacting degrees
Bounds on skewness and kurtosis of steady state currents
Current fluctuations are a powerful tool to unreaveal the underlying physics of the observed transport process. This work discusses some general properties of the third and the fourth cumulant of the


Universal form of thermodynamic uncertainty relation for Langevin dynamics.
The TUR formulation presented here can be regarded as the universal form of the TUR for general Langevin dynamics and it is shown that the original TUR is a consequence of the underdamped TUR in the zero-mass limit.
Thermodynamic uncertainty relation for underdamped Langevin systems driven by a velocity-dependent force.
This study presents a TUR, applicable to a system driven by a velocity-dependent force in the context of underdamped Langevin dynamics, by extending the theory of Vu and Hasegawa, and shows that it accurately describes the trade-off properties of a molecular refrigerator (cold damping), Brownian dynamics in a magnetic field, and an active particle system.
Unified approach to classical speed limit and thermodynamic uncertainty relation.
This work obtains a universal lower bound on the total entropy production in terms of probability distributions of an observable in the time forward and backward processes and demonstrates that a generalized thermodynamic uncertainty relation can be derived from another particular case of the universal relation.
Uncertainty relations for underdamped Langevin dynamics.
By employing information inequalities, it is proved that for underdamped Langevin dynamics, the relative fluctuation of a current at a steady state is constrained by both the entropy production and the average dynamical activity.
Measuring the Thermodynamic Cost of Timekeeping
All clocks, in some form or another, use the evolution of nature towards higher entropy states to quantify the passage of time. Due to the statistical nature of the second law and corresponding
A generalization of the thermodynamic uncertainty relation to periodically driven systems
The thermodynamic uncertainty relation expresses a universal trade-off between precision and entropy production, which applies in its original formulation to current observables in steady-state
Thermodynamic Uncertainty Relation for Arbitrary Initial States.
This work derives a finite-time TUR valid for arbitrary initial states from the Cramér-Rao inequality and finds that the variance of an accumulated current is bounded from below by the instantaneous current at the final time, which suggests that "the boundary is constrained by the bulk".
Bounds on current fluctuations in periodically driven systems
Small nonequilibrium systems in contact with a heat bath can be analyzed with the framework of stochastic thermodynamics. In such systems, fluctuations, which are not negligible, follow universal
Cost and Precision of Brownian Clocks
It is shown that a clock driven by a periodic variation of an external protocol can achieve arbitrary precision at arbitrarily low cost, which constitutes a fundamental difference between processesdriven by a fixed thermodynamic force and those driven periodically.
Free diffusion bounds the precision of currents in underdamped dynamics.
The properties of driven free diffusion in the underdamped regime are analyzed and it is shown that it inherently violates the overdamped TUR for finite times and a bound for one-dimensional driven diffusion in a potential is conjecture based on the result for free diffusion.
