Generalized laws of thermodynamics in the presence of correlations [PDF]

open access: yesNature Communications, 2017
In presence of inter-system correlations, violations of the laws of thermodynamics become possible. Here, the authors develop a formalism redefining heat, work and thermodynamic laws in terms of quantum conditional entropy, which consistently generalize ...

Quantum Thermodynamics: A Dynamical Viewpoint

open access: yesEntropy, 2013
Quantum thermodynamics addresses the emergence of thermodynamic laws from quantum mechanics. The viewpoint advocated is based on the intimate connection of quantum thermodynamics with the theory of open quantum systems. Quantum mechanics inserts dynamics

Thermodynamics of Various Entropies in Specific Modified Gravity with Particle Creation

open access: yesAdvances in High Energy Physics, 2018
We consider the particle creation scenario in the dynamical Chern-Simons modified gravity in the presence of perfect fluid equation of state p=(γ-1)ρ. By assuming various modified entropies (Bekenstein entropy logarithmic entropy, power law correction ...

The Third Law of Thermodynamics [PDF]

open access: bronzeThe Journal of Chemical Physics, 1934
The invariance of statistical weights requires that the entropy of any phase approach zero at 0°K. The uncertainty principle, however, makes it impossible to define a state of absolute zero for a substance whose lowest energy states are closely spaced multiplets.

Scale-Invariant Rotating Black Holes in Quadratic Gravity

open access: yesEntropy, 2015
Black hole solutions in pure quadratic theories of gravity are interesting since they allow the formulation of a set of scale-invariant thermodynamics laws.

Thermodynamics at microscales: 3D→2D, 1D and 0D

open access: yesGreen Energy & Environment, 2020
Today, the laws of traditional thermodynamics are facing challenges when science is growing rapidly toward the microscale-world, even quantum hypothesis.

Dynamic Equilibrium Equations in Unified Mechanics Theory

open access: yesApplied Mechanics, 2021
Traditionally dynamic analysis is done using Newton’s universal laws of the equation of motion. According to the laws of Newtonian mechanics, the x, y, z, space-time coordinate system does not include a term for energy loss, an empirical damping term “C”

Thermodynamics of an accelerated expanding universe [PDF]

open access: yes, 2005
We investigate the laws of thermodynamics in an accelerating universe driven by dark energy with a time-dependent equation of state. In the case we consider that the physically relevant part of the Universe is that envelopped by the dynamical apparent ...
