Information and the second law of thermodynamics [PDF]
arXiv, 2018 The second law of classical thermodynamics, based on the positivity of the entropy production, only holds for deterministic processes. Therefore the Second Law in stochastic quantum thermodynamics may not hold. By making a fundamental connection between thermodynamics and information theory we will introduce a new way of defining the Second Law which ...

How Did We Get Here? The Tangled History of the Second Law of Thermodynamics [PDF]
arXiv, 2023 An extensive survey is given of the historical origins of the Second Law of thermodynamics, illustrated by excerpts from many original sources, and with biographical information about key contributors. The major strands of conceptual development of the Second Law are traced, in particular showing how persistent beliefs about it emerged.

Thermodynamics in Modified Gravity with Curvature Matter Coupling
Advances in High Energy Physics, 2013 The first and generalized second laws of thermodynamics are studied in f(R,Lm) gravity, a more general modified theory with curvature matter coupling. It is found that one can translate the Friedmann equations to the form of first law accompanied with ...

Clausius’ Disgregation: A Conceptual Relic that Sheds Light on the Second Law
Entropy, 2015 The present work analyzes the cognitive process that led Clausius towards the translation of the Second Law of Thermodynamics into mathematical expressions.

Notes on the Generalised Second Law of Thermodynamics [PDF]
arXiv, 1997 Several comments are given to previous proofs of the generalised second law of thermodynamics: black hole entropy plus ordinary matter entropy never decreases for a thermally closed system. Arguments in favour of its truism are given in the spirit of conventional thermodynamics.

Generalized second law of thermodynamics in massive gravity
European Physical Journal C: Particles and FieldsHere, we study the generalized second law (GSL) of thermodynamics in the framework of massive gravity. To do this, we consider a FRW universe filled only with matter and enclosed by the apparent horizon.

Weakly nonlocal non-equilibrium thermodynamics - variational principles and Second Law [PDF]
in Applied Wave Mathematics, Springer, 2009 pp153-186., 2009 A general, uniform, rigorous and constructive thermodynamic approach to weakly nonlocal non-equilibrium thermodynamics is reviewed. A method is given to construct and restrict the evolution equations of physical theories according to the Second Law of thermodynamics and considering weakly nonlocal constitutive state spaces.

Viscous dark energy and generalized second law of thermodynamics
, 2011 We examine the validity of the generalized second law of thermodynamics in a non-flat universe in the presence of viscous dark energy. At first we assume that the universe filled only with viscous dark energy.

Shannon Meets Carnot: Generalized Second Thermodynamic Law [PDF]
, 2008 The classical thermodynamic laws fail to capture the behavior of systems with energy Hamiltonian which is an explicit function of the temperature. Such Hamiltonian arises, for example, in modeling information processing systems, like communication channels, as thermal systems.

The second law and beyond in microscopic quantum setups
, 2018 The Clausius inequality (CI) is one of the most versatile forms of the second law. Although it was originally conceived for macroscopic steam engines, it is also applicable to quantum single particle machines.
