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…
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…
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…
