Entropy current and entropy production in relativistic spin hydrodynamics [PDF]
Physics Letters B, 2023 We use a first-principle quantum-statistical method to derive the expression of the entropy production rate in relativistic spin hydrodynamics. We show that the entropy current is not uniquely defined and can be changed by means of entropy-gauge ...

Deep learning probability flows and entropy production rates in active matter. [PDF]
Proc Natl Acad Sci U S A, 2023 Significance A long-standing challenge in statistical mechanics has been to quantify the nonequilibrium nature of active systems such as swarming bacteria, schooling fish, and flocking birds.

Relating a System's Hamiltonian to Its Entropy Production Using a Complex Time Approach. [PDF]
Entropy (Basel), 2023 We exploit the properties of complex time to obtain an analytical relationship based on considerations of causality between the two Noether-conserved quantities of a system: its Hamiltonian and its entropy production. In natural units, when complexified,

Field theories of active particle systems and their entropy production [PDF]
Reports on progress in physics. Physical Society, 2022 Active particles that translate chemical energy into self-propulsion can maintain a far-from-equilibrium steady state and perform work. The entropy production measures how far from equilibrium such a particle system operates and serves as a proxy for the

Geometrical aspects of entropy production in stochastic thermodynamics based on Wasserstein distance [PDF]
Physical Review Research, 2021 We study a relationship between optimal transport theory and stochastic thermodynamics for the Fokker-Planck equation. We show that the lower bound on the entropy production is the action measured by the path length of the L^{2}-Wasserstein distance ...

Continuous Monitoring of Entropy Production and Entropy Flow in Humans Exercising under Heat Stress [PDF]
Entropy, 2023 Complex living systems, such as the human organism, are characterized by their self-organized and dissipative behaviors, where irreversible processes continuously produce entropy internally and export it to the environment; however, a means by which to ...

Foraging Dynamics and Entropy Production in a Simulated Proto-Cell [PDF]
Entropy, 2022 All organisms depend on a supply of energetic resources to power behavior and the irreversible entropy-producing processes that sustain them. Dissipative structure theory has often been a source of inspiration for better understanding the thermodynamics ...

Entropy Production in Exactly Solvable Systems [PDF]
Entropy, 2020 The rate of entropy production by a stochastic process quantifies how far it is from thermodynamic equilibrium. Equivalently, entropy production captures the degree to which global detailed balance and time-reversal symmetry are broken.
