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.

How “Berry Phase” Analysis of Non-Adiabatic Non-Hermitian Systems Reflects Their Geometry

open access: yesEntropy, 2023
There is currently great interest in systems represented by non-Hermitian Hamiltonians, including a wide variety of real systems that may be dissipative and whose behaviour can be represented by a “phase” parameter that characterises the way “exceptional

Thermodynamics in f(G,T) Gravity

open access: yesAdvances in High Energy Physics, 2018
This paper explores the nonequilibrium behavior of thermodynamics at the apparent horizon of isotropic and homogeneous universe model in f(G,T) gravity (G and T represent the Gauss-Bonnet invariant and trace of the energy-momentum tensor, resp.).

Extended irreversible thermodynamics of heat transport. A brief introduction; pp. 118–126 [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2008
Current frontiers of technology require generalized transport equations incorporating memory, non-local effects, and non-linear effects. Extended Irreversible Thermodynamics provides such transport equations in a form compatible with the second law of ...

Fundamental science and medicine at the crossroads of life concept

open access: yesАкушерство, гинекология и репродукция, 2022
The laws of fundamental science dictate the rules of thinking. And the latter, in turn, form the methodology of science. With the discovery of the second law of thermodynamics, it became possible to approach the issues of the universe in a different way,

Second law of thermodynamics for batteries with vacuum state [PDF]

open access: yesQuantum, 2021
In stochastic thermodynamics work is a random variable whose average is bounded by the change in the free energy of the system. In most treatments, however, the work reservoir that absorbs this change is either tacitly assumed or modelled using ...

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
