A Rayleigh criterion for mechanical instability: inducing activity by chemo-mechanical coupling

Aaron Beyen, Francesco Casini, Christian Maes

Instabilities in thermodynamic systems are often undesirable, as they can lead to loss of control or even catastrophic behavior. Yet, the same mechanisms can also generate rich non…

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…

Specific heat of the driven Curie-Weiss model

Elena Rufeil Fiori, Christian Maes, Robbe Vidts

Applying a time-periodic magnetic field to the standard ferromagnetic Curie-Weiss model brings the spin system in a steady out-of-equilibrium condition. We recall how the hysteresi…

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…
