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…
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…
Heat capacity of periodically driven two-level systems
Elena Rufeil Fiori, Christian Maes
We define the heat capacity for steady periodically driven systems and as an example we compute it for dissipative two-level systems where the energy gap is time-modulated. There,…
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…
