Measuring thermodynamic length [PDF]
Phys. Rev. Lett. 99 100602 (2007), 2007 Thermodynamic length is a metric distance between equilibrium thermodynamic states. Among other interesting properties, this metric asymptotically bounds the dissipation induced by a finite time transformation of a thermodynamic system. It is also connected to the Jensen-Shannon divergence, Fisher information and Rao's entropy differential metric ...

AIP Conference Proceedings, 2008 Using Planck scale oscillators in the background dark energy in a model that parallels the theory of phonons, we deduce the Planck mass, the elementary particle mass scale, the mass of the Universe and a recently discovered residual energy in the cosmic background. We also deduce the Beckenstein temperature formula for black holes. Finally we show that

Thermodynamics and Rate Thermodynamics [PDF]
arXiv, 2023 Approach of mesoscopic state variables to time independent equilibrium sates (zero law of thermodynamics) gives birth to the classical equilibrium thermodynamics. Approach of fluxes and forces to fixed points (equilibrium fluxes and forces) that drive reduced mesoscopic dynamics gives birth to the rate thermodynamics that is applicable to driven ...

A unified view of polymer, dumbbell, and oligonucleotide DNA nearest-neighbor thermodynamics.
Proceedings of the National Academy of Sciences of the United States of America, 1998 A unified view of polymer, dumbbell, and oligonucleotide nearest-neighbor (NN) thermodynamics is presented. DNA NN DeltaG degrees 37 parameters from seven laboratories are presented in the same format so that careful comparisons can be made.

Black hole chemistry: thermodynamics with Lambda [PDF]
, 2016 We review recent developments on the thermodynamics of black holes in extended phase space, where the cosmological constant is interpreted as thermodynamic pressure and treated as a thermodynamic variable in its own right.

Thermodynamics of Schwarzschild-de Sitter black hole: thermal stability of Nariai black hole [PDF]
, 2008 We study thermodynamics of the Schwarzschild-de Sitter black hole in five dimensions by introducing two temperatures based on the standard and Bousso-Hawking normalizations. We use the first-law of thermodynamics to derive thermodynamic quantities.

Quasi-Homogeneous Thermodynamics and Black Holes [PDF]
J.Math.Phys. 44 (2003) 1089-1128, 2002 We propose a generalized thermodynamics in which quasi-homogeneity of the thermodynamic potentials plays a fundamental role. This thermodynamic formalism arises from a generalization of the approach presented in paper [1], and it is based on the requirement that quasi-homogeneity is a non-trivial symmetry for the Pfaffian form $\delta Q_{rev}$.

The postulates of gravitational thermodynamics [PDF]
, 1996 The general principles and logical structure of a thermodynamic formalism that incorporates strongly self-gravitating systems are presented. This framework generalizes and simplifies the formulation of thermodynamics developed by Callen.
