Negative Differential Heat Conductivity in a Harmonic Chain Coupled to a Particle Reservoir
Simon Krekels, Christian Maes, Ion Santra +1
When coupling thermal baths at different temperatures, negative differential thermal conductivity is typically attributed to nonlinear interactions in the connecting medium. In thi…
Quasistatic response for nonequilibrium processes: evaluating the Berry potential and curvature
Aaron Beyen, Faezeh Khodabandehlou, Christian Maes
We investigate how introducing slow, time-dependent perturbations to a steady, nonequilibrium process alters the expected (excess) values of important observables, such as the dyna…
Critical exponents of fluid-fluid interfacial tensions near a critical endpoint in a nonwetting gap
Joseph O. Indekeu, Kenichiro Koga
Fluid three-phase equilibria, with phases , are studied close to a tricritical point, analytically and numerically, in a mean-field density-functional theory with two dens…
Exact bound of power-efficiency trade-off in finite-time thermodynamic cycles
R. X. Zhai, Xin Yue, C. P. Sun
Power and efficiency are fundamental criteria for evaluating the performance of thermodynamic cycles. However, it is generally impossible to maximize both simultaneously. In partic…
Coupling an elastic string to an active bath: the emergence of inverse damping
Aaron Beyen, Christian Maes, Ji-Hui Pei
We consider a slow elastic string with Klein-Gordon dynamics coupled to a bath of run-and-tumble particles. We derive and solve the induced Langevin-Klein-Gordon string dynamics wi…
Transfer of active motion from medium to probe via the induced friction and noise
Ji-Hui Pei, Christian Maes
Can activity be transmitted from smaller to larger scales? We report on such a transfer from a homogeneous active medium to a Newtonian spherical probe. The active medium consists…
Negative specific heats: where Clausius and Boltzmann entropies separate
Lander Bogers, Faezeh Khodabandehlou, Christian Maes
Steady nonequilibria dissipate energy and, when changing external parameters, an extra or excess heat accompanies the relaxation to the new nonequilibrium condition. For nonequilib…
Affine relationships between steady currents
Faezeh Khodabandehlou, Christian Maes, Karel Netočný
Perturbing transition rates in a steady nonequilibrium system, e.g. modelled by a Markov jump process, causes a change in the local currents. Their susceptibility is usually expres…
Noether's theorem applied to GENERIC
Aaron Beyen, Christian Maes
The last decades have seen growing interest in connecting principles of thermodynamics with methods from analytical mechanics. The thermodynamic formalism has become an inspiring f…
First part of Clausius heat theorem in terms of Noether's theorem
Aaron Beyen, Christian Maes
After Helmholtz, the mechanical foundation of thermodynamics included the First Law , and the first part of the Clausius heat theorem . The res…
The induced friction on a probe moving in a nonequilibrium medium
Ji-Hui Pei, Christian Maes
Using a powerful combination of projection-operator method and path-space response theory, we derive the fluctuation dynamics of a slow inertial probe coupled to a steady nonequili…
Entropy as Noether charge for quasistatic gradient flow
Aaron Beyen, Christian Maes
Entropy increase is fundamentally related to the breaking of time-reversal symmetry. By adding the 'extra dimension' associated with thermodynamic forces, we extend that discrete s…
Acceleration from a clustering environment
Roi Holtzman, Christian Maes
We study the effects of correlations in a random environment on a random walker. The dependence of its asymptotic speed on the correlations is a nonperturbative effect as it is not…
Local detailed balance for active particle models
Faezeh Khodabandehlou, Christian Maes
Starting from a Huxley-type model for an agitated vibrational mode, we propose an embedding of standard active particle models in terms of two-temperature processes. One temperatur…
Promoting Fluctuation Theorems into Covariant Forms
Ji-Hui Pei, Jin-Fu Chen, H. T. Quan
The principle of covariance, a cornerstone of modern physics, asserts the equivalence of all inertial frames of reference. Fluctuation theorems, as extensions of the second law of…
Frenetic steering: nonequilibrium-enabled navigation
Bram Lefebvre, Christian Maes
We explain the steering of slow degrees of freedom by coupling them to driven components for which the time-symmetric reactivities are manipulated. We present the strategy and main…
Slow dissipation and spreading in disordered classical systems: A direct comparison between numerics and mathematical bounds
Wojciech De Roeck, François Huveneers, Oskar A. Prośniak
We study the breakdown of Anderson localization in the one-dimensional nonlinear Klein-Gordon chain, a prototypical example of a disordered classical many-body system. A series of…
Close-to-equilibrium heat capacity
Faezeh Khodabandehlou, Christian Maes
Close to equilibrium, the excess heat governs the static fluctuations. We study the heat capacity in that McLennan regime, i.e., in linear order around equilibrium, using an expres…
Phase diagram and specific heat of a nonequilibrium Curie-Weiss model
Aaron Beyen, Christian Maes, Irene Maes
Adding activity or driving to a thermal system may modify its phase diagram and response functions. We study that effect for a Curie-Weiss model where the thermal bath switches rap…
Mechanisms of DNA-mediated allostery
Midas Segers, Aderik Voorspoels, Takahiro Sakaue +1
Proteins often regulate their activities via allostery - or action at a distance - in which the binding of a ligand at one binding site influences the affinity for another ligand a…
Reentrant condensation transition in a model of driven scalar active matter with diffusivity edge
Jonas Berx, Aritra Bose, Ramin Golestanian +1
The effect of a diffusivity edge is studied in a system of scalar active matter confined by a periodic potential and driven by an externally applied force. We find that this system…
Specific heat of a driven lattice gas
Pritha Dolai, Christian Maes
Calorimetry for equilibrium systems aims to determine the available microscopic occupation and distribution of energy levels by measuring thermal response. Nonequilibrium versions…
Frenetic steering in a nonequilibrium graph
Bram Lefebvre, Christian Maes
In traditional recognition tasks of neural networks, a potential landscape or cost function guides the system toward patterns using gradient dynamics. That is not how the brain wor…
Wetting and nonwetting near a tricritical point
Joseph O. Indekeu, Kenichiro Koga
The dihedral contact angles between interfaces in three-fluid-phase equilibria must be continuous functions of the bulk thermodynamic fields. This general argument, which we propos…
