Traces of Quantum Gravity Effects at Late-time Cosmological Dynamics via Distance Measures

The Astrophysical Journal
Inspired by the entropy–area relation of black hole thermodynamics, we study the thermodynamics of the cosmological apparent horizon in a spatially flat Friedmann–Robertson–Walker universe in the framework of an extended uncertainty principle (EUP).

THERMODYNAMIC EXPRESSIONS FOR MELTING OF TWO COMPONENT COPOLYMERS

Sen'i Gakkaishi, 1973
As the representative theories on melting in copolymers composed of units of type A capable of crystallizing and other units B incapable of crystallizing, two theories proposed by P. J. Flory in 1949 and in 1955 are known well. However, there are not a few experimental results on melting in copolymers that can not be explained enough even with those ...

Equilibrium thermodynamics in modified gravitational theories

, 2010
We show that it is possible to obtain a picture of equilibrium thermodynamics on the apparent horizon in the expanding cosmological background for a wide class of modified gravity theories with the Lagrangian density $f(R, \phi, X)$, where $R$ is the ...

Modified theory of gravity and clustering of multi-component system of galaxies

European Physical Journal C: Particles and Fields, 2019
In this paper, we analyze the clustering of galaxies using a modified theory of gravity, in which the field content of general relativity has been be increased.

On Equivalence of Nonequilibrium Thermodynamic and Statistical Entropies

Entropy, 2015
We review the concept of nonequilibrium thermodynamic entropy and observables and internal variables as state variables, introduced recently by us, and provide a simple first principle derivation of additive statistical entropy, applicable to all ...

Timelike Boundary Sine-Gordon Theory and Two-Component Plasma

, 2007
It has long been known that there is a relation between boundary sine-Gordon theory and thermodynamics of charge neutral two-component Coulomb plasma on a unit circle.

Non-Fourier Heat Transfer with Phonons and Electrons in a Circular Thin Layer Surrounding a Hot Nanodevice

Entropy, 2015
A nonlocal model for heat transfer with phonons and electrons is applied to infer the steady-state radial temperature profile in a circular layer surrounding an inner hot component. Such a profile, following by the numerical solution of the heat equation,

Ab initio thermodynamic model of Cu$_2$ZnSnS$_4$ [PDF]

, 2014
Thin-film solar cells based on the semiconductor Cu$_2$ZnSnS$_4$ (CZTS) are a promising candidate for Terawatt-scale renewable energy generation. While CZTS is composed of earth abundant and non-toxic elements, arranged in the kesterite crystal structure, there is a synthetic challenge to produce high-quality stoichiometric materials over large areas ...
