Hamiltonian curl-forces in systems coupled to multiple thermal reservoirs
Omer Chor, Aljaž Godec, Oren Raz
We investigate the statistical mechanics of a system coupled to multiple heat reservoirs at different temperatures, a setting which typically sustains nontrivial circulation. By ap…
Thermodynamic Concentration Inequalities: Controlling Uncertainty in Finite-Time and Small-Sample Thermodynamic Inference
Rick Bebon, Aljaž Godec
We derive nonasymptotic upper bounds on the probability that a generalized current of a geometrically ergodic diffusion observed for any amount of time, or its sample mean over any…
Strong Mpemba Effect Through a Reentrant Phase Transition
Kristian Blom, Doron Benyamin, Uwe Thiele +2
We investigate temperature quenches across the reentrant phase transition of the antiferromagnetic Ising model in a magnetic field and show that it provides a natural mechanism for…
Thermal relaxation asymmetry persists under inertial effects
Cai Dieball, Aljaž Godec
Relaxation phenomena far from thermal equilibrium feature a rich phenomenology, including the thermal relaxation asymmetry. The latter states that heating occurs faster than coolin…
Dynamic Models for Two Nonreciprocally Coupled Fields: A Microscopic Derivation for Zero, One, and Two Conservation Laws
Kristian Blom, Uwe Thiele, Aljaž Godec
We construct dynamic models governing two nonreciprocally coupled fields for several cases with zero, one, and two conservation laws. Starting from two microscopic nonreciprocally…
Towards Markov-State Holography
Xizhu Zhao, Dmitrii E. Makarov, Aljaž Godec
Experiments, in particular on biological systems, typically probe lower-dimensional observables which are projections of high-dimensional dynamics. In order to infer consistent mod…
Thermodynamic correlation inequalities for finite times and transients
Cai Dieball, Aljaž Godec
Recently, a thermodynamic bound on correlation times was formulated in [A. Dechant, J. Garnier-Brun, S.-i. Sasa, Phys. Rev. Lett. 131, 167101 (2023)], showing how the decay of corr…
Concentration of Empirical First-Passage Times
Rick Bebon, Aljaz Godec
First-passage properties are central to the kinetics of target-search processes. Theoretical approaches so far primarily focused on predicting first-passage statistics for a given…
Hallmarks of Deception in Asset-Exchange Models
Kristian Blom, Dmitrii E. Makarov, Aljaž Godec
We investigate the transient and steady-state dynamics of the Bennati-Dragulescu-Yakovenko money game in the presence of probabilistic cheaters, who can misrepresent their financia…
Multiple Pareto-optimal solutions of the dissipation-adaptation trade-off
Jorge Tabanera-Bravo, Aljaž Godec
Adaptation refers to the ability to recover and maintain ``normal'' function upon perturbations of internal or external conditions and is essential for sustaining life. Biological…
Local Order Controls the Onset of Oscillations in the Nonreciprocal Ising Model
Kristian Blom, Uwe Thiele, Aljaž Godec
We elucidate the generic bifurcation behavior of local and global order in the nonreciprocal Ising model evolving under Glauber dynamics. We show that a critical magnitude of neare…
Model-free inference of memory in conformational dynamics of a multi-domain protein
Leonie Vollmar, Rick Bebon, Julia Schimpf +5
Single-molecule experiments provide insight into the motion (conformational dynamics) of individual protein molecules. Usually, a well-defined but coarse-grained intramolecular coo…
Thermodynamic bounds on generalized transport: From single-molecule to bulk observables
Cai Dieball, Aljaž Godec
We prove that the transport of any differentiable scalar observable in -dimensional non-equilibrium systems is bounded from above by the total entropy production scaled by the a…
On the emergence of memory in equilibrium versus non-equilibrium systems
Xizhu Zhao, David Hartich, Aljaž Godec
Experiments often probe observables that correspond to low-dimensional projections of highdimensional dynamics. In such situations distinct microscopic configurations become lumped…
Milestoning estimators of dissipation in systems observed at a coarse resolution: When ignorance is truly bliss
Kristian Blom, Kevin Song, Etienne Vouga +2
Many non-equilibrium, active processes are observed at a coarse-grained level, where different microscopic configurations are projected onto the same observable state. Such "lumped…
Asymmetric Thermal Relaxation in Driven Systems: Rotations go Opposite Ways
Cai Dieball, Gerrit Wellecke, Aljaž Godec
It was predicted and recently experimentally confirmed that systems with microscopically reversible dynamics in locally quadratic potentials warm up faster than they cool down. Thi…
Controlling Uncertainty of Empirical First-Passage Times in the Small-Sample Regime
Rick Bebon, Aljaž Godec
We derive general bounds on the probability that the empirical first-passage time of a reversible ergodic Markov process inferred from a samp…
On correlations and fluctuations of time-averaged densities and currents with general time-dependence
Cai Dieball, Aljaž Godec
We present technical results required for the description and understanding of correlations and fluctuations of the empirical density and current as well as diverse time-integrated…
Direct Route to Thermodynamic Uncertainty Relations and Their Saturation
Cai Dieball, Aljaž Godec
Thermodynamic uncertainty relations (TURs) bound the dissipation in non-equilibrium systems from below by fluctuations of an observed current. Contrasting the elaborate techniques…
Feynman-Kac theory of time-integrated functionals: Itô versus functional calculus
Cai Dieball, Aljaž Godec
The fluctuations of dynamical functionals such as the empirical density and current as well as heat, work and generalized currents in stochastic thermodynamics are usually studied…
Coarse Graining Empirical Densities and Currents in Continuous-Space Steady States
Cai Dieball, Aljaž Godec
We present the conceptual and technical background required to describe and understand the correlations and fluctuations of the empirical density and current of steady-state diffus…
Comment on "Inferring broken detailed balance in the absence of observable currents"
David Hartich, Aljaž Godec
We present a simple biophysical example that invalidates the main conclusion of "Nat. Commun. 10, 3542 (2019)". Moreover, we explain that systems with one or more hidden states bet…
Violation of Local Detailed Balance Despite a Clear Time-Scale Separation
David Hartich, Aljaž Godec
Integrating out fast degrees of freedom is known to yield, to a good approximation, memory-less, i.e. Markovian, dynamics. In the presence of such a time-scale separation local det…
Scattering fingerprints of two-state dynamics
Cai Dieball, Diego Krapf, Matthias Weiss +1
Particle transport in complex environments such as the interior of living cells is often (transiently) non-Fickian or anomalous, that is, it deviates from the laws of Brownian moti…
