The Hungry Daemon: Does an Energy-Harvesting Active Particle Have to Obey the Second Law of Thermodynamics? [PDF]

open access: yesEntropy (Basel)
Thought experiments like Maxwell’s Demon or the Smoluchowski–Feynman Ratchet can help in pursuing the microscopic origin of the Second Law of Thermodynamics. Here we present a more sophisticated mechanical system than a ratchet, consisting of

Mechanical Proof of the Second Law of Thermodynamics Based on Volume Entropy [PDF]

open access: yes, 2007
In a previous work (M. Campisi. Stud. Hist. Phil. M. P. 36 (2005) 275-290) we have addressed the mechanical foundations of equilibrium thermodynamics on the basis of the Generalized Helmholtz Theorem.

Emergence of the second law out of reversible dynamics [PDF]

open access: yes, 2009
If one demystifies entropy the second law of thermodynamics comes out as an emergent property entirely based on the simple dynamic mechanical laws that govern the motion and energies of system parts on a micro-scale.

The generalized second law of thermodynamics with Barrow entropy

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
We investigate the validity of the generalized second law of thermodynamics, applying Barrow entropy for the horizon entropy. The former arises from the fact that the black-hole surface may be deformed due to quantum-gravitational effects, quantified by ...

Gravitational Entropy and the Second Law of Thermodynamics

open access: yesEntropy, 2015
The spontaneous violation of Lorentz and diffeomorphism invariance in a phase near the big bang lowers the entropy, allowing for an arrow of time and the second law of thermodynamics. The spontaneous symmetry breaking leads to

The Second Law of Thermodynamics in Bioenergetics [PDF]

open access: yesProceedings of the National Academy of Sciences, 1974
Bioenergetic processes are viewed as processes of free energy transduction. The free energies of both local equilibrium and fluctuation states are being considered. It is shown that the exchange of thermal energy with the surrounding medium, acting as a reservoir, does not violate the second law of thermodynamics within broad limits.

Thermodynamics as Control Theory [PDF]

open access: yes, 2013
I explore the reduction of thermodynamics to statistical mechanics by treating the former as a control theory: a theory of which transitions between states can be induced on a system (assumed to obey some known underlying dynamics) by means of operations
