Algebraical Entropy and Arrow of Time [PDF]
Entropy 24 (2022) 1522, 2022 Usually, it is supposed that irreversibility of time appears only in macrophysics. Here, we attempt to introduce the microphysical arrow of time assuming that at a fundamental level nature could be non-associative. Obtaining numerical results of a measurement, which requires at least three ingredients: object, device and observer, in the non ...

Arrow of time and gravitational entropy in collapse [PDF]
Classical and Quantum GravityWe investigate the status of the gravitational arrow of time in the case of a spherical collapse of a fluid that conducts heat and radiates energy. In particular, we examine the results obtained by W. B. Bonnor in his 1985 paper where he found that the gravitational arrow of time was opposite to the thermodynamic arrow of time.

Beyond the Arrow of Time: Can There Be a Relation between the Measurement of Entropy and Time? [PDF]
Proceedings, 2017 The general tendency of the entropy of an isolated to increase is considered to be directly linked to the direction of the flow of time. This raises the question whether a quantitative relation can be established such that a time interval can be measured

Entropy, Information and Complexity or Which Aims the Arrow of Time? [PDF]
Entropy, 2015 In 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 ...

Is the Hypothesis About a Low Entropy Initial State of the Universe Necessary for Explaining the Arrow of Time? [PDF]
Phys. Rev. D 94, 023520 (2016), 2016 According to statistical mechanics, micro-states of an isolated physical system (say, a gas in a box) at time $t_0$ in a given macro-state of less-than-maximal entropy typically evolve in such a way that the entropy at time $t$ increases with $|t-t_0|$ in both time directions.

Entropy and the arrow of time in population dynamics [PDF]
Biosystems, 2022 The concept of entropy in statistical physics is related to the existence of irreversible macroscopic processes. In this work, we explore a recently introduced entropy formula for a class of stochastic processes with more than one absorbing state that is extensively used in population genetics models.

Arrow of Time, Entropy, and Protein Folding: Holistic View on Biochirality [PDF]
International Journal of Molecular Sciences, 2022 Chirality is a universal phenomenon, embracing the space–time domains of non-organic and organic nature. The biological time arrow, evident in the aging of proteins and organisms, should be linked to the prevalent biomolecular chirality. This hypothesis drives our exploration of protein aging, in relation to the biological aging of an organism.

Entropy and Cosmological Arrows of Time [PDF]
arXiv, 2021 Deutsch and Aguirre have recently shown that the solutions of certain dynamical systems typically contain a point of minimum size that they identify as an entropy minimum and from which the size and entropy increase to infinity in both directions of time.

Pre-bangian origin of our entropy and time arrow [PDF]
Physics Letters B, 1999 I argue that, in the chaotic version of string cosmology proposed recently, classical and quantum effects generate, at the time of exit to radiation, the correct amount of entropy to saturate a Hubble (or holography) entropy bound (HEB) and to identify, within our own Universe, the arrow of time.
