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.

Entropy, Information, and the Arrow of Time
The 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.

Fractals, Entropy and the Arrow of Time
, 2016 Why can we not move backward in time? According to Relativity, time is just one more dimension like length, width and height where we can go as easily backward as forward. What makes time special? Newton’s laws are symmetric in time and so is even Schrodinger’s equation which controls the happenings at the quantum level.

Entropy, Information, and Complexity or Which Aims the Arrow of Time? Scientific Explanation
New Visions in Biological Science Vol. 3, 2021In this article, we analyze the interrelationships among such notions as entropy, information, complexity, order and chaos and show using the theory of categories how to generalize the second law of thermodynamics as a law of increasing generalized entropy or a general law of complification.

Work fluctuation, entropy, and time’s arrow in time-asymmetric engine cycles
Journal of Physics A: Mathematical and Theoretical, 2020We 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.

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.

Vacuum Radiation, Entropy and the Arrow Of Time
, 2002 The root mean square perturbations on particles produced by vacuum radiation must be limited by the uncertainty principle, i.e., 1/2 1/2 =ħ/2, where 1/2 and 1/2 are the root mean square values of drift in spatial and momentum coordinates. The value 1/2 =(ħt/m) 1/2 , where m is the mass of the particle, can be obtained both from classical SED ...

The Arrow of Time, Entropy and the Expansion of the Universe
, 1976 Setting aside the guidance of consciousness, we discover a signpost for time in the physical world itself. The signpost is a rather peculiar one, and I would not venture to say that the discovery of the signpost amounts to the same thing as the discovery of an objective ‘going on of time’ in the universe.
