CYNAR: a trajectory-based estimator of entropy production
Marco Baiesi, Ivan DI Terlizzi
Inferring the entropy production rate from recorded trajectories is a key challenge in stochastic thermodynamics. In experiments, the forces governing the dynamics are usually…
Variance sum rule: proofs and solvable models
Ivan Di Terlizzi, Marco Baiesi, Felix Ritort
We derive, in more general conditions, a recently introduced variance sum rule (VSR) [I. Di Terlizzi et al., 2024 Science 383 971] involving variances of displacement and force imp…
Constrained hidden Markov models reveal further Hsp90 protein states
Riccardo Tancredi, Antonio Feltrin, Giosuè Sardo Infirri +4
Time series of conformational dynamics in proteins are usually evaluated with hidden Markov models (HMMs). This approach works well if the number of states and their connectivity i…
Effective estimation of entropy production with lacking data
Marco Baiesi, Tomohiro Nishiyama, Gianmaria Falasco
Observing stochastic trajectories with rare transitions between states, practically undetectable on time scales accessible to experiments, makes it impossible to directly quantify…
Generalized equipartition for nonlinear multiplicative Langevin dynamics: application to laser-cooled atoms
Gianmaria Falasco, Eli Barkai, Marco Baiesi
The virial theorem, and the equipartition theorem in the case of quadratic degrees of freedom, are handy constraints on the statistics of equilibrium systems. Their violation is in…
A thermodynamic uncertainty relation for a system with memory
Ivan Di Terlizzi, Marco Baiesi
We introduce an example of thermodynamic uncertainty relation (TUR) for systems modeled by a one-dimensional generalised Langevin dynamics with memory, determining the motion of a…
Explicit solution of the generalised Langevin equation
Ivan Di Terlizzi, Felix Ritort, Marco Baiesi
Generating an initial condition for a Langevin equation with memory is a non trivial issue. We introduce a generalisation of the Laplace transform as a useful tool for solving this…
Rate dependence of current and fluctuations in jump models with negative differential mobility
Gianluca Teza, Stefano Iubini, Marco Baiesi +2
Negative differential mobility is the phenomenon in which the velocity of a particle decreases when the force driving it increases. We study this phenomenon in Markov jump models w…
Kinetic uncertainty relation
Ivan Di Terlizzi, Marco Baiesi
Relative fluctuations of observables in discrete stochastic systems are bounded at all times by the mean dynamical activity in the system, quantified by the mean number of jumps. T…
Life efficiency does not always increase with the dissipation rate
Marco Baiesi, Christian Maes
There does not exist a general positive correlation between important life-supporting properties and the entropy production rate. The simple reason is that nondissipative and time-…
Thermal response of a Fermi-Pasta-Ulam chain with Andersen thermostats
Federico D'Ambrosio, Marco Baiesi
The linear response to temperature variations is well characterised for equilibrium systems but a similar theory is not available, for example, for inertial heat conducting systems…
A general fluctuation-response relation for noise variations and its application to driven hydrodynamic experiments
Cem Yolcu, Antoine Bérut, Gianmaria Falasco +3
The effect of a change of noise amplitudes in overdamped diffusive systems is linked to their unperturbed behavior by means of a nonequilibrium fluctuation-response relation. This…
Thermal response of nonequilibrium RC-circuits
Marco Baiesi, Sergio Ciliberto, Gianmaria Falasco +1
We analyze experimental data obtained from an electrical circuit having components at different temperatures, showing how to predict its response to temperature variations. This il…
Self-similar aftershock rates
Jörn Davidsen, Marco Baiesi
In many important systems exhibiting crackling noise --- intermittent avalanche-like relaxation response with power-law and, thus, self-similar distributed event sizes --- the "law…
Linear response of hydrodynamically-coupled particles under a nonequilibrium reservoir
Cem Yolcu, Marco Baiesi
A recent experiment driving colloids electromagnetically, by Bérut et al. [2014 Europhys. Lett. 107, 60004], is an ideal paradigm for illustrating a linear response theory for none…
Role of trapping and crowding as sources of negative differential mobility
Marco Baiesi, Attilio L. Stella, Carlo Vanderzande
Increasing the crowding in an environment does not necessarily trigger negative differential mobility of strongly pushed particles. Moreover, the choice of the model, in particular…
Temperature response in nonequilibrium stochastic systems
Gianmaria Falasco, Marco Baiesi
The linear response to temperature changes is derived for systems with overdamped stochastic dynamics. Holding both in transient and steady state conditions, the results allow to c…
Inflow rate, a time-symmetric observable obeying fluctuation relations
Marco Baiesi, Gianmaria Falasco
While entropy changes are the usual subject of fluctuation theorems, we seek fluctuation relations involving time-symmetric quantities, namely observables that do not change sign i…
Energy repartition for a harmonic chain with local reservoirs
Gianmaria Falasco, Marco Baiesi, Leo Molinaro +2
We exactly analyze the vibrational properties of a chain of harmonic oscillators in contact with local Langevin heat baths. Nonequilibrium steady-state fluctuations are found to be…
Knotted globular ring polymers: how topology affects statistics and thermodynamics
Marco Baiesi, Enzo Orlandini, Attilio L. Stella
The statistical mechanics of a long knotted collapsed polymer is determined by a free-energy with a knot-dependent subleading term, which is linked to the length of the shortest po…
Thermal response in driven diffusive systems
Marco Baiesi, Urna Basu, Christian Maes
Evaluating the linear response of a driven system to a change in environment temperature(s) is essential for understanding thermal properties of nonequilibrium systems. The system…
Rotational dynamics of entangled polymers
Jean-Charles Walter, Michiel Laleman, Marco Baiesi +1
Some recent results on the rotational dynamics of polymers are reviewed and extended. We focus here on the relaxation of a polymer, either flexible or semiflexible, initially wrapp…
Models of DNA denaturation dynamics: universal properties
Marco Baiesi, Enrico Carlon
We briefly review some of the models used to describe DNA denaturation dynamics, focusing on the value of the dynamical exponent , which governs the scaling of the characteristi…
Universal properties of knotted polymer rings
Marco Baiesi, Enzo Orlandini
By performing Monte Carlo sampling of -steps self-avoiding polygons embedded on different Bravais lattices we explore the robustness of universality in the entropic, metric and…
