Entropy, Information, and the Arrow of Time

Journal of Physical Chemistry B, 2010
We shall investigate the relationships between the thermodynamic entropy and information theory and the implications that can be drawn for the arrow of time. This demands a careful study of classical thermodynamics and a review of its fundamental concepts.

Transfer Entropy in Physical Systems and the Arrow of Time

Physical Review E, 2016
Recent developments have cemented the realization that many concepts and quantities in thermodynamics and information theory are shared. In this paper, we consider a highly relevant quantity in information theory and complex systems, the transfer entropy, and explore its thermodynamic role by considering the implications of time reversal upon it.

From Randomness and Entropy to the Arrow of Time

The Element reconstructs, analyses and compares different derivational routes to a grounding of the Arrow of Time in entropy. It also evaluates the link between entropy and visible disorder, and the related claim of an alignment of the Arrow of Time with a development from order to visible disorder.

Influence of Thermodynamic Arrow of Time on Entropy

Physical Science International Journal, 2023
This study assessed the influence of thermodynamic arrow of time on entropy for boiled cooling water (physical process), the universe and the air (natural process). This was done by determining the entropies of boiled water, the universe and air. This was achieved by using 1.5 litres of pure water, a 2 liter electric kettle, a digital thermometer, a ...

Entropy, inflation and the arrow of time

Classical and Quantum Gravity, 1991
One of the motivations for the introduction of inflation was to explain the large entropy of the observed Universe. Penrose has recently pointed out that the entropy of the observable Universe is small when compared with the maximal possible entropy. The authors show that this phenomenon is also a natural consequence of inflation.

Work fluctuation, entropy, and time’s arrow in time-asymmetric engine cycles

Journal of Physics A: Mathematical and Theoretical, 2020
Abstract We derive a thermodynamic uncertainty relation that governs the work yield and the entropy production of an engine operating with a time-asymmetric cycle such as the Carnot cycle. The relation shows an intercorrelation between one engine cycle and its time-reversed cycle, disclosing the role of the time-asymmetry of an engine
