Entropy and Frenesy: the arrow and the bustle of time
Christian Maes
Nonequilibrium statistical mechanics is the science of time as it manifests itself in the transient or steady entropy producing dynamical condition of many-body systems. Beyond the…
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…
Bringing calorimetry (back) to life
Faezeh Khodabandehlou, Christian Maes, Ãdgar Roldán
Micro-calorimetry offers significant potential as a quantitative method for studying the structure and function of biological systems, for instance, by probing the excess heat rele…
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 NetoÄný
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…
