Thermodynamics of black holes: an analogy with glasses

, 1998
The present equilibrium formulation of thermodynamics for black holes has several drawbacks, such as assuming the same temperature for black hole and heat bath. Recently the author formulated non-equilibrium thermodynamics for glassy systems.

Off-equilibrium confined dynamics in a glassy system with level-crossing states

, 2006
We study analytically the dynamics of a generalized p-spin model, starting with a thermalized initial condition. The model presents birth and death of states, hence the dynamics (even starting at equilibrium) may go out of equilibrium when the ...

Thermodynamics for non-equilibrium pattern formation

AIP Advances, 2011
The second entropy theory for non-equilibrium thermodynamics is used to show that the optimum structure or pattern of a time-dependent system corresponds to the maximum entropy. A formula for the total entropy of convective heat flow is derived.

Cosmological and thermodynamics analysis in Weyl gravity

European Physical Journal C: Particles and Fields, 2020
In the framework of modified Weyl gravity, we observe the equilibrium picture of the thermodynamical laws for flat Friedmann–Robertson–Walker metric with chameleon scalar field and analyze the validity of the generalized second law of thermodynamics and ...

Nonlinear Dynamical Equation for Irreversible, Steepest-Entropy-Ascent Relaxation to Stable Equilibrium

, 2007
We discuss the structure and main features of the nonlinear evolution equation proposed by this author as the fundamental dynamical law within the framework of Quantum Thermodynamics.

Thermodynamic analysis of modified teleparallel gravity involving higher-order torsion derivative terms

European Physical Journal C: Particles and Fields, 2019
The present study is elaborated to investigate the validity of thermodynamical laws in a modified teleparallel gravity based on higher-order derivative terms of torsion scalar.

Open system trajectories specify fluctuating work but not heat

, 2016
Based on the explicit knowledge of a Hamiltonian of mean force, the classical statistical mechanics and equilibrium thermodynamics of open systems in contact with a thermal environment at arbitrary interaction strength can be formulated.

Thermodynamics in $f(R)$ gravity in the Palatini formalism

, 2010
We investigate thermodynamics of the apparent horizon in $f(R)$ gravity in the Palatini formalism with non-equilibrium and equilibrium descriptions. We demonstrate that it is more transparent to understand the horizon entropy in the equilibrium framework

Entropy correction and phase transition of n-dimensional charged dilaton dS black holes

European Physical Journal C: Particles and Fields
The manifest disparity in Hawking radiation temperatures between black hole and cosmological horizons in de Sitter (dS) spacetime reveals a non-equilibrium thermal configuration, inherently violating thermodynamic stability criteria. This asymmetry poses

New formulation of local-equilibrium thermodynamics

AIP Advances, 2019
This study points out that the conventional separation of balance equations for energy in fluids into a flow and a source term is not thermodynamically valid.
