Local Detailed Balance in the Lorenz Model: Replaces the Butterfly with Frenetic Bursting
Faezeh Khodabandehlou, Christian Maes
The Lorenz system is the canonical low-order model of convective instability, yet its dissipative and driving terms have never been checked against, nor constructed from, an explic…
Critical behavior of the driven Curie-Weiss model
Ruohan Xu, Faezeh Khodabandehlou, Christian Maes
We complete the phase diagram of the macroscopic Curie-Weiss magnet in a time-periodic external field, as a function of temperature and driving parameters. There is a regime (large…
Specific heat of thermally driven chains
Michiel Gautama, Faezeh Khodabandehlou, Christian Maes +1
We investigate the thermal responses of a harmonic oscillator chain coupled at its boundaries to heat baths held at different temperatures. This setup sustains a steady energy flux…
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…
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…
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…
Nonequilibrium Third Law of Thermodynamics
Faezeh Khodabandehlou
The extended Third Law of thermodynamics for nonequilibrium jump processes is studied in previous collaborative papers (Kh et al.,2023) [1,2], where the nonequilibrium heat capacit…
The Sun within: active processes from two-temperature models
Faezeh Khodabandehlou, Christian Maes
We propose an embedding of standard active particle models in terms of two-temperature processes. One temperature refers to an ambient thermal bath, and the other temperature effec…
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…
The vanishing of excess heat for nonequilibrium processes reaching zero ambient temperature
Faezeh Khodabandehlou, Christian Maes, Irene Maes +1
We present the mathematical ingredients for an extension of the Third Law of Thermodynamics (Nernst heat postulate) to nonequilibrium processes. The central quantity is the excess…
Exact computation of heat capacities for active particles on a graph
Faezeh Khodabandehlou, Simon Krekels, Irene Maes
The notion of a nonequilibrium heat capacity is important for bio-energetics and for calorimetry of active materials more generally. It centers around the notion of excess heat or…
A Nernst heat theorem for nonequilibrium jump processes
Faezeh Khodabandehlou, Christian Maes, Karel Netočný
We discuss via general arguments and examples when and why the steady nonequilibrium heat capacity vanishes with temperature. The framework is the one of Markov jump processes on f…
Trees and forests for nonequilibrium purposes: an introduction to graphical representations
Faezeh Khodabandehlou, Christian Maes, Karel Netočný
Using local detailed balance we rewrite the Kirchhoff formula for stationary distribution of Markov jump processes in terms of a physically interpretable tree-ensemble. We use that…
