Quasi-static Decomposition and the Gibbs Factorial in Small Thermodynamic Systems
Journal of Statistical Physics, 2022 AbstractFor a classical system consisting of N-interacting identical particles in contact with a heat bath, we define the free energy from thermodynamic relations in equilibrium statistical mechanics. Concretely, the temperature dependence of the free energy is determined from the Gibbs-Helmholtz relation, and its volume dependence is determined from ...

Quasi-Static Hydrodynamic Limits [PDF]
Journal of Statistical Physics, 2015 We consider hydrodynamic limits of interacting particles systems with open boundaries, where the exterior parameters change in a time scale slower than the typical relaxation time scale. The limit deterministic profiles evolve quasi-statically.

Experimentally achieving minimal dissipation via thermodynamically optimal transport [PDF]
Nature CommunicationsOptimal transport theory, originally developed in the 18th century for civil engineering, has since become a powerful optimization framework across disciplines, from generative AI to cell biology. In physics, it has recently been shown to set fundamental

Thermodynamic Efficiency of Interactions in Self-Organizing Systems
Entropy, 2021 The emergence of global order in complex systems with locally interacting components is most striking at criticality, where small changes in control parameters result in a sudden global reorganization.

Trapped Ideal Bose Gas with a Few Heavy Impurities
Atoms, 2023 In this article, we formulate a general scheme for the calculation of the thermodynamic properties of an ideal Bose gas with one or two immersed static impurities, when the bosonic particles are trapped in a harmonic potential with either a quasi-1D or ...

Stability and phase transition of rotating Kaluza–Klein black holes
European Physical Journal C: Particles and Fields, 2021 In this paper, we investigate the thermodynamics and phase transitions of a four-dimensional rotating Kaluza–Klein black hole solution in the presence of Maxwell electrodynamics. Calculating the conserved and thermodynamic quantities shows that the first

Energy Dissipation and Information Flow in Coupled Markovian Systems
Entropy, 2018 A stochastic system under the influence of a stochastic environment is correlated with both present and future states of the environment. Such a system can be seen as implicitly implementing a predictive model of future environmental states.
