Edge Currents Shape Condensates in Chiral Active Matter
Boyi Wang, Patrick Pietzonka, Frank Jülicher
Chiral active matter, which breaks both parity symmetry and time-reversal symmetry, is ubiquitous in living systems. Here, we introduce a minimal two-dimensional chiral active latt…
Accuracy Comes at a Cost: Optimal Localisation Against a Flow
Till Welker, Patrick Pietzonka
How much work does it cost for a propelled particle to stay localised near a stationary target, defying both thermal noise and a constant flow that would carry it away? We study th…
Condensate Formation in a Chiral Lattice Gas
Boyi Wang, Frank Jülicher, Patrick Pietzonka
We investigate the formation of condensates in a binary lattice gas in the presence of chiral interactions. These interactions differ between a given microscopic configuration and…
Thermodynamic cost for precision of general counting observables
Patrick Pietzonka, Francesco Coghi
We analytically derive universal bounds that describe the trade-off between thermodynamic cost and precision in a sequence of events related to some internal changes of an otherwis…
Second law for active heat engines
Arya Datta, Patrick Pietzonka, Andre C Barato
Macroscopic cyclic heat engines have been a major motivation for the emergence of thermodynamics. In the last decade, cyclic heat engines that have large fluctuations and operate a…
Classical pendulum clocks break the thermodynamic uncertainty relation
Patrick Pietzonka
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…
Cycle counts and affinities in stochastic models of non-equilibrium systems
Patrick Pietzonka, Jules Guioth, Robert L. Jack
For non-equilibrium systems described by finite Markov processes, we consider the number of times that a system traverses a cyclic sequence of states (a cycle). The joint distribut…
Autonomous engines driven by active matter: Energetics and design principles
Patrick Pietzonka, Étienne Fodor, Christoph Lohrmann +2
Because of its nonequilibrium character, active matter in a steady state can drive engines that autonomously deliver work against a constant mechanical force or torque. As a generi…
A generalization of the thermodynamic uncertainty relation to periodically driven systems
Timur Koyuk, Udo Seifert, Patrick Pietzonka
The thermodynamic uncertainty relation expresses a universal trade-off between precision and entropy production, which applies in its original formulation to current observables in…
Large Deviation Function for a Driven Underdamped Particle in a Periodic Potential
Lukas P. Fischer, Patrick Pietzonka, Udo Seifert
Employing large deviation theory, we explore current fluctuations of underdamped Brownian motion for the paradigmatic example of a single particle in a one dimensional periodic pot…
Fluctuations of Apparent Entropy Production in Networks with Hidden Slow Degrees of Freedom
Matthias Uhl, Patrick Pietzonka, Udo Seifert
The fluctuation theorem for entropy production is a remarkable symmetry of the distribution of produced entropy that holds universally in non-equilibrium steady states with Markovi…
Entropy production of active particles and for particles in active baths
Patrick Pietzonka, Udo Seifert
Entropy production of an active particle in an external potential is identified through a thermodynamically consistent minimal lattice model that includes the chemical reaction pro…
Universal trade-off between power, efficiency, and constancy in steady-state heat engines
Patrick Pietzonka, Udo Seifert
Heat engines should ideally have large power output, operate close to Carnot efficiency and show constancy, i.e., exhibit only small fluctuations in this output. For steady-state h…
Finite-time generalization of the thermodynamic uncertainty relation
Patrick Pietzonka, Felix Ritort, Udo Seifert
For fluctuating currents in non-equilibrium steady states, the recently discovered thermodynamic uncertainty relation expresses a fundamental relation between their variance and th…
Universal bound on the efficiency of molecular motors
Patrick Pietzonka, Andre C. Barato, Udo Seifert
The thermodynamic uncertainty relation provides an inequality relating any mean current, the associated dispersion and the entropy production rate for arbitrary non-equilibrium ste…
Affinity- and topology-dependent bound on current fluctuations
Patrick Pietzonka, Andre C. Barato, Udo Seifert
We provide a proof of a recently conjectured universal bound on current fluctuations in Markovian processes. This bound establishes a link between the fluctuations of an individual…
Extreme fluctuations of active Brownian motion
Patrick Pietzonka, Kevin Kleinbeck, Udo Seifert
In active Brownian motion, an internal propulsion mechanism interacts with translational and rotational thermal noise and other internal fluctuations to produce directed motion. We…
Universal bounds on current fluctuations
Patrick Pietzonka, Andre C. Barato, Udo Seifert
For current fluctuations in non-equilibrium steady states of Markovian processes, we derive four different universal bounds valid beyond the Gaussian regime. Different variants of…
Fine-structured large deviations and the fluctuation theorem: Molecular motors and beyond
Patrick Pietzonka, Eva Zimmermann, Udo Seifert
By considering subexponential contributions in large deviation theory, we determine the fine structure in the probability distribution of the observable displacement of a bead coup…
