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…
An agitated oscillator chain
Aaron Beyen, Christian Maes, Ion Santra
We study how the stationary dynamics of an oscillator chain is modified when coupled to a bath of run-and-tumble particles. First, assuming time-scale separation, we derive the ind…
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…
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…
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…
